Assisted Reproductive Technology (ART) is a collection of techniques that help facilitate pregnancy (e.g. invitro fertilization). A 2008 report by the Centers for Disease Control and Prevention estimated that ART hasbeen successful in leading to a live birth in 31% of cases. A new fertility clinic claims that their success rateis higher than average. Using a random sample, 12 of 30 patients were successful. A consumer watchdoggroup would like to determine if this provides strong evidence to support the company's claim.a) Write the hypotheses to test if the success rate for ART at this clinic is significantly different than the31% success rate reported by the CDC.Ho: Select an answer=HA: Select an answerb) What is the null value?c) What is the point estimate?d) Describe a setup for a simulation that would be appropriate in this situation and how the p-value can becalculated using the simulation results.• To simulate the null value of, grab 100 cards and marka success.Thoroughly shuffle the cards and draw 1.

A tire manufacturer has been producing tires with an average life expectancy of 28,000 miles. Now the company is advertising that its new tires' life expectancy has increased. In order to test the legitimacy of the advertising campaign, an independent testing agency tested a sample of 12 of their tires and has provided the following data. Longevity (In Thousands of Miles) 28.0 26.5 27.2 26.0 28.3 26.4 29.1 25.0 28.1 27.7 28.3 26.9 a. Determine the mean and the standard deviation. Formulate the correct hypotheses to determine whether b. or not the tire company is using legitimate advertising. At the .05 level of significance using the critical value approach, test to determine whether or not the tire company is using legitimate advertising. Assume the population is normally distributed. d. Repeat the test using the p-value approach. C.
According to the most recent General Social Survey, 70% of adults watch TV nightly. A researcher believes that the proportion of college students who watch TV nightly is less than this. To test this claim the research samples 400 college students and finds that 276 watch TV nightly. At the 0.05 level of significance does this data provide evidence to suggest that the proportion of college students who watch TV nightly is less than 70%? Select the correct hypothesis test for this problem:
The Wisconsin Fish and Game Department stocked a lake with 30% catfish, 15 % bass, 40% bluegill, and 15% Northern Pike. Five years later they took a random sample of 500 fish from the lake and found 120 catfish, 85 bass, 220 bluegill, and 75 Northern Pike. At the 5% level of significance, can we show that the distribution of fish changed over the 5-year interval? State and test appropriate hypotheses. State conclusions.
A nonprofit company concerned with the school dropout rates has designed a tutoring program aimed at students between 16 to 18 years old. A national center for educational statistics reported that the high school dropout rate for the year 2000 was 10.9%.One school district, who adopted the use of the nonprofit's tutoring program and whose dropout rate has always been very close to the national average, reported in 2004 that 158 of their 1769 students dropped out. Is their experience evidence that the tutoring program has been effective? Determine the hypotheses for this test. Choose the correct answer below A. H0: p=0.109 HA: p≠0.109 B.

According to the American Lung association, lung cancer account for 28% of all cancer deaths in the US. A new type of screening for lung cancer, computed tomography (CT), has been developed. Medical researchers believe CT scans are scans are more sensitive than regular X-rays in pinpointing small tumors. The Cancer Center at the University of South Florida is currently conducting a clinical trial of 50,000 smokers nationwide to compare the effectiveness of CT scans with X-ray for detecting lung cancer (Today’s Tomorrows, Fall 2002). Each participating smoker is randomly assigned to one of the two screening methods, CT or chest X-ray, and his or her progress is tracked over time. The age at which the scanning method first detects a tumor is the variable of interest. A. Identify the data collection method used by the cancer researchers. B. dentify experimental units of the study. C. Identify the type of the variable measured. D. Identify the population and sample.
An analyst from the UK Office of Statistics is investigating the provision of social support services throughout the city of Manchester. For each borough in the city they will establish the required level of support based on the percentage of residents below the poverty line. They take a random sample of 122 individuals in the borough of Bury and find that 25 have annual net-income below the poverty line. The analyst will decide to provide Bury with additional social services support if the sample data provides sufficient evidence that the true proportion of people living below poverty line is greater than 17%. A test of hypothesis is conducted. What is the null hypothesis? The true proportion of Bury inhabitants below the poverty line is lower than 0.17. The true proportion of Bury inhabitants below the poverty line is greater than 0.17. The sample proportion of Bury inhabitants below the poverty line is lower than 0.17. The sample proportion of Bury inhabitants below the poverty…
Acne is a common skin disease that affects most adolescents and can continue into adulthood. A study compared the effectiveness of three acne treatments and a placebo, all in gel form, applied twice daily for 12 weeks. The study's 517 teenage volunteers were randomly assigned to one of the four treatments. Success was assessed as clear or almost clear skin at the end of the 12 week period. The results of the study can be seen in the table below. Using the appropriate statistical test, determine if there is significant evidence that the four treatments perform differently. If so, how do they compare.
Dental health issues remain a barrier to attendance, as evidenced by a 2010 Los Angeles School Attendance Review Board (SARB), which lists dental health, along with homelessness, in the top barriers to attendance. The Dental Hygiene program at West Los Angeles College collects data on its clinic patients to help instructors and students better understand their patient population. From July 2017 to December 2019 the program treated 3421 patients. Students were asked to analyze a random sample of 127 patients from that time period and found that 36.4% had severe periodontal disease (infections and inflammation of the gums and bone that surround and support the teeth). Identify the population: Identify the sample: Identify the parameter of interest: Identify the statistic:
Over the past few decades, public health officials have examined the link between weight concerns and teen girls' smoking. Researchers surveyed a group of 273 randomly selected teen girls living in Massachusetts (between 12 and 15 years old). After four years the girls were surveyed again. Sixty-three said they smoked to stay thin. Is there good evidence that more than thirty percent of the teen girls smoke to stay thin? Correctly identify the null and alternative hypotheses:
Mood variation is related to photoperiod in some people, and the likelihood of depression increases in the winter months. As a result, people often assume that suicide rates increase in winter. A study in Finland (Valtonen et al. 2006) divided the year 1997 into equal halves and compared the number of suicides in “winter” (24 September to 19 March) and “summer” (remainder of year). Out of a total of 1636 suicides, 766 were in winter and 870 were in the summer. Based on these data, estimate the proportion of suicides that occurred in winter, assuming that the suicides were independent. Are the data compatible with a greater suicide rate in winter than summer, based on a 95% confidence interval?
A team of epidemiologists at the Mayo Clinic wanted to find whether there is an association between obesity and cardiovascular disease (CVD). They conducted a prospective cohort study following obese and non-obese individuals who were free of CVD at the beginning of study for five years.
