A better drug? In a pilot study, a company's newcholesterol-reducing drug outperforms the currentlyavailable drug. If the data provide convincing evi-dence that the mean cholesterol reduction with thenew drug is more than 10 milligrams per deciliterof blood (mg/dl) greater than with the current drug,the company will begin the expensive process ofmass-producing the new drug. For the 14 subjectswho were assigned at random to the current drug,the mean cholesterol reduction was 54.1 mg/dl witha standard deviation of 11.93 mg/dl. For the 15 sub-jects who were randomly assigned to the new drug,the mean cholesterol reduction was 68.7 mg/dl witha standard deviation of 13.3 mg/dl. Graphs of thedata reveal no outliers or strong skewness.Carry out an appropriate significance test. Whatconclusion would you draw? (Note that the nullhypothesis is not Ho: μμ2=0.)Based on your conclusion in part (a), could you havemade a Type I error or a Type II error? Justify youranswer.

A researcher would like to examine how the chemical tryptophan, contained in foods such as turkey, can affect mental alertness. A sample of n = 9 college students is obtained and each student's performance on a familiar video game is measured before and after eating a traditional Thanksgiving dinner including roast turkey. The average score dropped by M = 14 points after the meal with SS = 1152 for the difference scores. What statistical procedure would you use to analyze this data and why?
A study of iron deficiency among infants compared different feeding regimens. One group contain breast fed infants, while the other group received a standard baby formula without iron supplements. After six months the hemoglobin levels in the infants' blood were measured. The table summarizes these results. 23 breast fed babies: mean hemoglobin = 13.3 with a st. dev. = 1.7, 19 formula fed babies: mean hemoglobin = 12.4 with a st. dev. = 1.8. Sample Size Mean Standard Deviation Breast fed 23 13.3 1.7 Formula fed 19 12.4 1.8 You will be using a 95% level of confidence to estimate the difference in hemoglobin levels between the two groups. You may assume both samples come from normally distributed populations. Please fill in the blank and answer questions below using the prompt above. The right hand critical value is . Round to 3 decimal places. The margin of error, rounded to 3 decimal places, is . Construct the 95% confidence interval estimate of the difference…
Many people take ginkgo supplements advertised to improve memory. Are these over-the- counter supplements effective? In a study, elderly adults were assigned to the treatment group or control group. The 104 participants who were assigned to the treatment group took 40 mg of ginkgo 3 times a day for 6 weeks. The 115 participants assigned to the control group took a placebo pill 3 times a day for 6 weeks. At the end of 6 weeks, the Wechsler Memory Scale was administered. Higher scores indicate better memory function. Summary values are given in the following table: Ginkgo 104 5.7 0.6 Placebo 115 5.5 0.5 Perform the appropriate test to determine if taking 40mg of ginkgo 3 times a day is effective in increasing mean performance on the Wechsler Memory Scale. > Is the study observational or designed experiment? > Can you conclude association or causation with this type of study? > Is this a matched-pair dependent test or two-sample independent test?

A study is run to estimate the incidence of atrial fibrillation (AF) in men and women over the age of 60. Development of atrial fibrillation was monitored over a 10-year follow-up period. The data are summarized below. Using this data, compute the cumulative incidence of AF in men and in women, the relative risk of AF incidence comparing men to women, and the odds ratio of AF incidence comparing men and women. Developed AF Did not Develop AF Men 120 6453 Women 86 7074
A recent study investigated whether the number of positive health behaviors (e.g., exercising, eating healthy) is predictive of a person's score on a happiness index, such that as positive health behaviors go up, happiness goes up. The results from the study, which was conducted with 12 people, were as follows: r = 0.63 and SSY = 56.0. What is the MSregression? What is the MSresidual? What is the calculated test statistic? Given the value of your calculated test statistic and your critical test statistic, do you reject the null?
The DASS-21 questionnaire is a validated measure of depression, anxiety, and stress. For the general population, the mean for anxiety is µ = 4.2. Anxiety levels are calculated based on self-reported answers to questions on a scale from 0 through 42, with lower scores indicating lower anxiety. Participants with gastrointestinal issues (specifically inflammatory bowel disease, IBD) completed the DASS-21. Use the data presented below to determine whether having gastrointestinal issues like IBD significantly increases risk for anxiety. Test whether or not the performance of this sample is significantly higher than the normal population using the proper t-test. Here are the data: Anxiety scores: 12, 15, 10, 8, 10, 5, 10, 13, 4, 6 ANALYSES AND UNGRADED OPTIONAL GUIDING QUESTIONS: 1a.

Dr. S. compared her experimental group to a control group using a t test and concluded that her t was significant at the 1% level. If Dr. S. replicates her study using a similar sample of participants, she is most likely: to find that the experimental group is different from the control group; to find that the experimental group is similar to the control group; to find that the distribution of scores in the experimental group resembles a normal curve; however, the distribution of scores in the control group does not resemble a normal curve; d. The experimental group scores were correlated with the control group scores
Foot ulcers are a common problem for people with diabetes. Higher skin temperatures on the foot indicate an increased risk of ulcers. The article "An Intelligent Insole for Diabetic Patients with the Loss of Protective Sensation" (Kimberly Anderson, M.S. Thesis, Colorado School of Mines), reports measurements of temperatures, in °F, of both feet for 181 diabetic patients. The results are presented in the following table. Left Foot Right Foot 80 80 85 85 75 80 88 86 89 87 87 82 78 78 88 89 89 90 76 81 89 86 87 82 78 78 80 81 87 82 86 85 76 80 88 89 Construct a scatterplot of the right foot temperature (y) versus the left foot temperature (x). Verify that a linear model is appropriate. b. Compute the least-squares line for predicting the right foot temperature from the left foot temperature. If the left foot temperatures of two patients differ by 2 degrees, by how much would you predict their right foot temperatures to differ? Predict the right foot temperature for a patient whose left…
Variation in gasoline mileage among makes and models of automobiles is influenced substantially by the weight and horsepower of the vehicles. An automobile manufacturer would like to determine if heavier cars consumer more gas than lighter cars. He collects data on 25 heavy and 25 light cars to test this hypothesis. What analysis would you complete to answer this question?
Roy ‘s Texaco wants to keep the price of its unleaded gasoline competitive with that of other stations in the area. Roy’s is currently charging $1.29 per gallon. To check that the average price for this gasoline for all stations within a 15 mile radius is higher than his price, Roy randomly samples the price of unleaded gasoline at ten stations located in this area. He obtains the following data for the price per gallon (in dollars): 1.7, 1.5, 2.6, 2.2, 2.4, 2.3, 2.6, 3.0, 1.4, 2.3 Set up the appropriate hypotheses and test them using a significance level of α= .05
