The Centers for Disease Control and Prevention (CDC) is required by law to publish a report on assisted reproductive technology (ART). ART includes all fertility treatments in which both the egg and the sperm are used. These procedures generally involve removing eggs from a woman's ovaries, combining them with sperm in the laboratory, and returning them to the woman's body or giving them to another woman.

- Does regular exercise reduce the risk of a heart attack? Provided are two ways to study this question. 1. A researcher finds 2000 men older than age 40 who exercise regularly and have not had heart attacks. She matches each with a similar man who does not exercise regularly, and she follows both groups for 5 years. 2. Another researcher finds 4000 men older than age 40 who have not had heart attacks and are willing to participate in a study. She assigns 2000 of the men to a regular program of supervised exercise. The other 2000 continue their usual habits. The researcher follows both groups for 5 years. Select the correct explanation clearly detailing why the second design will produce more trustworthy data. Choose one or more correct explanations. The first design is an observational study whereas the second design is an experiment. Assigning subjects to treatments, as in the second design, avoids confounding. In the second design, the subjects are chosen in a random fashion, whereas…Studies have shown that omega-3 fatty acids have a wide variety of health benefits. Omega-3 oils can be found in foods such as fish, walnuts, and flaxseed. A company selling milled flaxseed advertises that one tablespoon of the product contains, on average, at least 3800 mg of ALNA, the primary omega-3. a) The company plans to conduct a test to ensure that there is sufficient evidence that its claimiscorrect. Tobesafe,thecompanywantstomakesurethatevidenceshowsthe average is higher than 3800 mg. What are the null and alternative hypotheses? b) Suppose, instead, that a consumer organization plans to conduct a test to see if there is evidence against the claim that the product contains an average of 3800 mg per tablespoon. The consumer organization will only take action if it finds evidence that the claim made by the company is false and that the actual average amount of omega-3 is less than 3800 mg. What are the null and alternative hypotheses?How many have HIV? Researchers from Yale, working with medical teams in Tanzania, wanted to know how common infection with HIV, the virus that causes AIDS, is among pregnant women in that African country. To do this, they planned to test blood samples drawn from pregnant women. Yale’s institutional review board insisted that the researchers get the informed consent of each woman and tell her the results of the test. This is the usual procedure in developed nations. The Tanzanian government did not want to tell the women why blood was drawn or tell them the test results. The government feared panic if many people turned out to have an incurable disease for which the country’s medical system could not provide care. The study was canceled. Do you think that Yale was right to apply its usual standards for protecting subjects?
- Please help me work through the attached question?. Dr. Cooky, the head of the Food Administration, encourages Filipinos to monitor their calorie intake and aim for 500 calories a meal only; so that internationally approved minimum daily requirements will be achieved. He then wants to specifically test whether women who always order fast food meals can achieve this so that their daily calorie intakes would be 1,500 on average. A survey was done to monitor the calorie intake of 1,200 randomly selected women who always order fast food meals. Part of the analysis done resulted in a 95% confidence interval for the true mean calorie intake of women who always order fast food meals of [1791.51,1808.49]. The statistic of interest in symbols is .In words, it is the daily calorie intake of 1,200 randomly selected women who always order fast food meals. Based on the result, if the sampling process of randomly selecting 1,200 target samples is repeated a large number of times, 95% of the constructed intervals would contain the true average daily…The report Controlling Road Rage: A Literature Review and Pilot Study was prepared for the AAA Foundation for Traffic Safety by D. Rathbone and J. Huckabee. The authors discussed the results of a literature review and pilot study on how to prevent aggressive driving and road rage. Road rage is defined as “… an incident in which an angry or impatient motorist or passenger intentionally injures or kills another motorist, passenger, or pedestrian, or attempts or threatens to injure or kill another motorist, passenger, or pedestrian.” One aspect of the study was to investigate road rage as a function of the day of the week. The following table provides a frequency distribution for the days on which 69 road-rage incidents occurred. Day Frequency Sunday 5 Monday 5 Tuesday 11 Wednesday 12 Thursday 11 Friday 18 Saturday 7 At the 5% significance level, do the data provide sufficient evidence to conclude that road-rage incidents are more likely to occur on…
- Pharmaceutical companies spend billions of dollars per year on research and development of new drugs. The pharmaceutical company must subject each new drug to lengthy and involved testing before receiving the necessary permission from the Food and Drug Administration (FDA) to market the drug. The FDA's policy is that the pharmaceutical company must provide substantial evidence that a new drug is safe prior to receive FDA approval so that the FDA can confidently certify the safety of the drug to potential consumers.a.) If the new drug testing were to be placed in a test of hypothesis framework, would the null hypothesis be that the drug is safe or unsafe? The alternative hypothesis? (In an actual test, "safety" could be quantified using population parameters.) Fill in the blanks below.The null hypothesis would be that the drug is Select an answer unsafe safe and the alternative hypothesis would be that the drug is Select an answer unsafe safe. b.) Describe the Type I and Type II errors…A research wants to determine if pre-natal exposure to the hormones in birth control pills alters the sex makeup of midshipman fish populations (which are typically half male and half female).Specifically, the researcher wishes to test the hypothesis that exposure to hormones will increase the number of females in the population.The researcher exposes a group of pregnant midshipman fish to birth control hormones and records the sex of the first 19 offspring birthed.They then observe that 0 are female.Use a sign test to test the indicated hypothesis.What is the obtained value?A research wants to determine if pre-natal exposure to the hormones in birth control pills alters the sex makeup of midshipman fish populations (which are typically half male and half female).Specifically, the researcher wishes to test the hypothesis that exposure to hormones will increase the number of females in the population.The researcher exposes a group of pregnant midshipman fish to birth control hormones and records the sex of the first 11 offspring birthed.They then observe that 1 are female.Use a sign test and a alpha of .05 to test the indicated hypothesis.What is the critical value?
- The owner of a small clothing store is concerned that only 28% of people who enter her store actually buy something. A marketing salesman suggests that she invest in a new line of celebrity mannequins (think Seth Rogan modeling the latest jeans...). He loans her several different "people" to scatter around the store for a two-week trial period. The owner carefully counts how many shoppers enter the store and how many buy something so that at the end of the trial she can decide if she'll purchase the mannequins. She'll buy the mannequins if there is evidence that the percentage of people that buy something increases. a) Write the owner's null and alternative hypotheses. b) In this context describe a Type I error and the impact such an error would have on the store. c) In this context describe a Type II error and the impact such an error would have on the store. d) Based on data that she collected during the trial period the store's owner found that a 98% confidence interval for the…The NIH is funding a trial for a new antidepressant drug. A sample of 1000 people with severe depression are recruited and, at baseline, are given a questionnaire asking about their demographic characteristicsand their mental health. They are then randomly assigned to one of two groups. The treatment group receives the new antidepressant, a pill that must be taken twice a day. The control group receives a placebo pill containing nothing medically active, which must also be taken twice a day. After 10 weeks, researchers locate the individuals and ask them to fill out a questionnaire again assessing their mental health. At the end of the study, researchers find no statistically significant difference in the mental health of the treatment and control groups. Q: Should we be concerned about unbalanced groups here? Is it possible to empirically explore whether this is a problem for this study?Automobile racing, high-performance driving schools, and driver education programs run by automobile clubs continue to grow in popularity. All these activities require the participant to wear a helmet that is certified by the Snell Memorial Foundation, a not-for-profit organization dedicated to research, education, testing, and development of helmet safety standards. Snell "SA" (Sports Application) rated professional helmets are designed for auto racing and provide extreme impact resistance and high fire protection. One of the key factors in selecting a helmet is weight, since lower weight helmets tend to place less stress on the neck. The following data show the weight and price for 18 SA helmets (SoloRacer website).
