6. Analysis of variance has long been used in providing evidence of the effectiveness of pharmaceutical drugs.Such evidence is required before Philippine Food and Drugs Authority (PFDA) will allow a drug to bemarketed. In a recent test of the effectiveness of a new sleeping pill, three groups of 25 patients eachwere given the following treatments. The first group was given the drug, the second group was given theplacebo, and the third group was given no treatment at all. The number of minutes it took each person tofall asleep was recorded. The results are as follows:Drug group:12 17 34 115 42 18 272 37 50 32 12 27 21 10433 63 22 41 19 28 29 8Placebo group:44 32 28 30 22 123 12 42 13 27 54 56 32 37 2822 22 249 204 13 42 67No treatment group: 32 33 21 12 15 14 55 67 721 44 60 36 38 49 6689 63 2369 56 28 39 59Use Analysis of Variance to determine whether the drug is effective.

An epidemiologist found five cases of “big toe cancer” in the Yukon Territory. Because there were only a few cases, the epidemiologist decided to conduct a matched case-control study to determine whether shoe size larger than 9 is a risk factor for big toe cancer. Cases were individually matched to one control for daily activity, history of athlete’s foot, and history of ingrown toenails. The following data were gathered: Shoe size > 9 Pair Case Control 1 Yes No 2 No No 3 No Yes 4 Yes Yes 5 No Yes Compute the proper measure of association. Interpret your results. If you were to investigate a rare cancer in Lynchburg, where might you look for data? What would be necessary legally and ethically to be able to utilize this data set(s)?

A recent report stated that less than 35 percent of the adult residents in a certain city will be able to pass a physical fitness test. Consequently, the city’s Recreation Department is trying to convince the City Council to fund more physical fitness programs. The council is facing budget constraints and is skeptical of the report. The council will fund more physical fitness programs only if the Recreation Department can provide convincing evidence that the report is true. The Recreation Department plans to collect data from a sample of 185 adult residents in the city. A test of significance will be conducted at a significance level of =.05 for the following hypotheses. H0:p=.35 Ha:p<.35 where p is the proportion of adult residents in the city who are able to pass the physical fitness test. (a) Describe what a Type II error would be in the context of the study, and also describe a consequence of making this type of error. (b) The Recreation Department recruits 185 adult…
After the measles outbreak, the barangay captain of Big Rock wanted to assess the satisfaction of the residents to his actions during the outbreak. He then obtained a random sample of 5 residents per block (Block 1 to Block 5) and asked them their satisfaction (1 – very dissatisfied, 2- dissatisfied, 3- satisfied, 4- very satisfied). He wanted to know if the satisfaction of his residents differs across blocks. i. True or False: We should test the normality of responses per blocks before we proceed with the test of hypothesis on comparing these responses across blocks. ii. The appropriate alternative hypothesis in symbols is? a) At least one µi # µj, for izj, i,j=1,2,3,4,5 b) At least one Mdi + Mdj, for i#j, i,j=1,2,3,4,5 c ) μ1 μ2-μ3-μ4 μ5 d) Md1= Md2 = Md3 = Md4 = Md5 iii.

2. According to the Center for Disease Control (CDC), 69% of adults 20 years of age and over in the U.S. are overweight. Recently, Jackson County was ranked 48th (out of 83 counties in Michigan) for a healthy population, and the County Commission wants to know if the county is significantly different from the national average at a 0.10 level of significance. They take a random sample of 280 adult residents of the county who are 20 years of age or older, and find that 72.5% are classified as overweight. Test the researcher's claim showing all steps, work and graphs.
Researchers investigate how the presence of cell phones influence the quality of human interaction. Subjects are randomly selected from a population and divided into an experimental group that is asked to leave their phones in the front of the room and a control group that are not asked to leave their cell phones at the front of the room. Subjects are left alone for 10 minutes and then asked to take a survey designed to measure quality of interactions they had with others in the experiment. What statistical test is appropriate?
Results from the National Health and Nutrition Examination Survey (NHANES) conducted thirty years ago revealed that out of 378 randomly selected adults in the United States 57 were considered to be obese. In this year’s National Health and Nutrition Examination Survey, out of 426randomly selected adults in the United States 135 were considered to be obese. Based on these results, can one conclude, at the 0.01 level of significance, that the percentage of adults in the United States that are obese is considerably higher now than it was thirty years ago?

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.
A large company that produces allergy medications claims that Americans lose an average of 40 hours of work to problems related to seasonal allergies. A consumer advocacy group believes that company's claim exhibits self-interest bias. In other words, the advocacy group believes that the actual mean number of missed hours is less than claimed. The advocacy group would like to obtain statistical evidence about this issue and takes a random sample of 100 American workers. They find that these 100 people lost and average of 38 hours due to seasonal allergy symptoms. The standard deviation is 9.5 hours. (c) Based on your selection from part (b), what is the value of the standardized test statistic for this significance test? (d) Based on your selection from part (b), what is the P-value for this significance test? (e) What is the correct decision for this test, using a 0.05 level of signifcance? A) Reject the null hypothesis B) Do not reject the null…
