A paper investigated the driving behavior of teenagers by observing their vehicles as they left a high school parking lot and then again at a site approximately mile from the school. Assume that it isreasonable to regard the teen drivers in this study as representative of the population of teen drivers.Amount by Which SpeedLimit Was ExceededFemaleDriver-0.10.41.10.71.11.20.10.90.50.5(a) Use a .01 level of significance for any hypothesis tests. Data consistent with summary quantities appearing in the paper are given in the table. The measurements represent the difference betweenthe observed vehicle speed and the posted speed limit (in miles per hour) for a sample of male teenage drivers and a sample of female teenage drivers. (Use males - females: Round your test statisticto two decimal places. Round your degrees of freedom down to the nearest whole number. Round your p-value to three decimal places.)t=df =P =MaleDriver1.41.20.92.10.71.331.30.62.1(b) Do these data provide convincing support for the claim that, on average, male teenage drivers exceed the speed limit by more than do female teenage drivers?YesO No

ReAb. a question can influence eyewitness memory. In the study, college students watched a film of ap automobile accident and then were asked questions about what they saw. One group was asked, "About how fast were the cars going when they smashed into each other?" Another group was asked the same question except the verb was changed to "hit" in- stead of "smashed into." The "smashed into" group reported significantly higher estimates of speed than the "hit" group. Suppose a researcher repeats this study with a sample of today's college students and obtains the following results. Estimated Speed Smashed into Hit n 15 n = 15 M = 40.8 M = 34.0 SS = 510 SS = 414 a. Do the results indicate a significantly higher esti- mated speed for the "smashed into" group?

Suppose a new drug is proposed to lower total cholesterol. A study is designed to evaluate the ecacy of the drug in lowering cholesterol. Fifteen patients are enrolled in the study and asked to take the new drug for 6 weeks. At the end of 6 weeks, each patient’s total cholesterol level is measured and the sample statistics are as follows:n = 15, x̄ = 195.9, and s = 28.7. Is there statistical evidence of a reduction in mean total cholesterol in patients after using the new drug for 6 weeks? 27.
