An automobile club comes to the aid of stranded motorists who are members. Over the long run, about 5% of the members utilize this service in any 12 month period. A small town has 770 membersof the club. Consider the 770 members to be representative of the larger club membership. Let p be the proportion of them who require aid in a 12 month period. Based on the Empirical Rule, whatinterval should fall about 95% of the time? (Round all answers to the nearest hundredth.)andbetween

Thirty different video games showing drug use were observed. The duration times of drug use (in seconds) were recorded. When using this sample for a t test of the claim that the population mean is greater than 92 sec, what does df denote, and what is its value? what's the value of df?
Use the results from a survey of a simple random sample of 1064 adults. Among the 1064 respondents, 69% rated 13 themselves as above average drivers. We want to test the claim that more than 20 of adults rate themselves as above average drivers. Complete parts (a) through (e). A. No. Assuming quality of driving can be quantified, half of all adults must have driving quality less than or equal to the mean. B. Yes. Assuming quality of driving can be quantified, a distribution that is extremely skewed to the right would be the most promising scenario for more than this proportion of adults to have driving quality that is above the mean. C. Yes. Assuming quality of driving can be quantified, a distribution that is extremely skewed to the left would be the most promising scenario for more than this proportion of adults to have driving quality that is above the mean. O D. No. It is impossible to compare the quality of different adults' driving. b. If we use the same significance level to…
An automobile club comes to the aid of stranded motorists who are members. Over the long run, about 10% of the members utilize this service in any 12 month period. A small town has 240 members of the club. Consider the 240members to be representative of the larger club membership. Let p̂ be the proportion of them who require aid in a 12 month period. Based on the Empirical Rule, what interval should p̂ fall about 95% of the time? (Round all answers to the nearest hundredth.)

A medical doctor is interested in determining whether mean body temperatures are different in the morning and at night. Five patients were recruited and their body temperatures were measured first at 8 AM and then again at 10 PM. The data is in the following table: Patient 1 3 14 5 Morning 98.0 97.6 97.2 97.0 98.0 Night 97.0 98.8 97.6 97.7 98.8 For this matched pairs experiment, you should take the differences by calculating: Morning Night.
