Dr. S. Oberman has the research hypothesis that drivers who have consumed one drink are actually slightly better (score higher on a driving test) than drivers who have had no alcohol. (One drink, she believes, makes them relaxed and not as nervous.) She tests this by having subjects take a standard driving test. We know that completely sober, college-student drivers score an average of 75 on this test, where high scores mean better driving. Dr. S. Oberman's null hypothesis is: [note: Ho means mu, the population mean according to the null hypothesis] Ho is equal to 0 Po is less than 0 Po is not known, nor can it be known Ho is equal to (or less than) 75 Po is greater than 75
Several states have argued that the 65-mph speed limit has no justification and have refused to enforce it. The federal Department of Transportation (DOT) believes that the 65-mph limit saves lives. To illustrate its contention, the department regressed the number of traffic fatalities (Y) last year in a state on the state’s population (X1), the number of days of snow cover (X2), and the average speed of all cars (X3). The results are shown below. Table 10: Model Summary Model R R Square Adjusted R Square Std. Error of the Estimate 1 .821 a .780 .613 3.258 a.

A serious side effect of allergy medicines is that they cause drowsiness, which can cause many problems for the individuals taking them. In recent years, a new non-drowsy allergy medicine has been developed. The company that created the medicine claims to be the first, once-a-day, non-drowsy allergy medicine (call it Medicine A). An independent research group wanted to check on this claim by comparing medicine A with another allergy medicine not advertised as non-drowsy (call it Medicine B). A random sample of 3,193 allergy sufferers was selected and each individual was randomly assigned to take either Medicine A or Medicine B. From the Medicine A group, 114 of 1,604 reported drowsiness and from the Medicine B group, 155 of 1,589 reported drowsiness. Calculate and label the two sample proportions separately. Next, calculate the difference between these sample proportions by subtracting (Medicine A – Medicine B). Complete these calculations by hand, label each of them, and…

You are interested in the relationship between exercise and anxiety. You therefore design two separate studies. Study 1: You give a questionnaire about exercise. This questionnaire yields a score between 0 and 30, with 0 being never exercises, and 30 being exercises near constantly. You also give a questionnaire about anxiety. This questionnaire yields a score between 0 and 50, with 0 being not anxious at all, and 50 being extremely anxious. You then see if scores on the exercise questionnaire are related to scores on the anxiety questionnaire. Study 2: You randomly assign individuals to one of two groups. Group 1 must exercise for an hour a day 5 days a week, for one month. Group 2 must not exercise at all for the whole month. After the month, you conduct a formal diagnostic interview with each person to determine their level of anxiety. This anxiety interview yields an anxiety scale between 1 and 20. You then see if mean anxiety, as measured by the interview, is significantly…
