Assume you perform a study to detect how using social networks affects people's hapiness level. You have 20 volunteers. Your study is planned as follows. All participants are known to be active users of social networks. First you ask every participant to fill in special questionary that allows you to estimate their hapiness level. After that all participants will avoid using of social networks for one week. After this week they complete similar questionary to detect their new level of hapiness. Then for each participants their new hapiness level is compared the initial one. Assume that for each participant their hapiness level is changed: either decreased or increased. Let X be the random variable that models the number of participants for who increased their happiness level. Let Xobs = 16, i.e. 16 out of 20 participants become more happy, and it's the only data you can make decision on. Your significance level is 5%.

You are a medical researcher that wants to determine if your new drug can lower people's blood pressure. You recruit 60 participants with high blood pressure to be part of your study. You randomly assign participants to one of three groups to receive either 10 mg of your drug, 5 mg, or 0 mg (given as a placebo control). After 2 weeks, participants' blood pressure is measured and you compare among the 3 groups. Which statistical test would be best to determine if there is a significant difference in blood pressure among the three groups? one-sample t-test related samples t-test independent samples t-test ANOVA
Assuming there are 150 students in our statistics class, 20 of you have received 4 hours of study strategies tutoring before this semester starts. What we have known is that the mean score of your final grades in our statistics class is 72 with a SD of 6 and the mean score of the 20 students who have received tutoring is 75 with a SD of 5. As the instructor of this course, I would like to know whether the tutoring has impacted your final grades. Please use the one sample Z-test to help me find out the correct answer.

You are a public health researcher. You want to see if the average age that a person starts smoking has changed over time. Smokers are recruited to answer a survey that asked at what age they started smoking. You divided participants into two groups, one is participants under the age of 30 and the second for participants over the age of 30. The average age for the two groups were compared. Which statistical test would be best to determine if there is a significant different in starting age between the two groups.

An important issue is whether there are racial differences in hypertension among children. We define hypertension as being above the 95th percentile for either systolic blood pressure (SBP) or diastolic blood pressure (DBP) among children of the same age, height, and sex. Since some of the children were observed at multiple visits, a GEE model was run of hypertension on ethnic group. There were three ethnic groups considered: Caucasian, African American, and Hispanic. The results among boys are given in Table 13.54. TABLE 13.54 Relationship between hypertension and ethnic group among 27,009 boys in the Pediatric Task Force Data Variable Regression Coefficient SE Intercept -2.07 0.026 African American 0.049 0.041 Hispanic 0.328 0.059 What is the estimated OR for hypertension comparing Hispanic boys vs. Caucasian boys? (Call this OR1.) What is a 95% CI for this estimate?
A psychological study wants to analyze the relationship between anxiety and binge drinking; a questionnaire for anxiety and questionnaire for binge drinking is administered to each subject. What would be a good statistical test to test the hypothesis?
A researcher is testing which animal performs better on the anxiety task that involves a stranger walking into the room. In one group they test dogs and another cats and see how long it takes the animal to approach the person “stranger”. Here is the data from 10 subjects that was recorded in seconds:Dogs: 120, 126, 140, 115, 112, 130, 125, 108, 128, 143Cats: 125, 140, 128, 133, 138, 129, 135, 129, 140, 125Which set of scores has a lower SEM? You should be able to do this just by looking at the raw scores, but of course you can do the math if it helps you answer the question.
