C) The width of Elly’s interval will be greater than the width of Drew’s interval. D) The width of Elly’s interval will be less than the width of Drew’s interval. E) The width of Elly’s interval will be equal to the width of Drew’s interval.
. A researcher collects a sample of 24 measurements from a population and wishes to find a 99% confidence interval for the population mean. What value should he use for t*? b. If he instead decides to use a 95% confidence interval, will the interval be wider or be narrower or stay the same? Why?
According to the same Pew Internet study, 8% of those with broadband connections are using fixed wireless. Let p be the proportion of broadband users who use fixed wireless, and consider the hypotheses: Ho: p = 0.08 Ha: p ≠ 0.08 If the p-value is 0.103 and we fail to reject H0, based upon the same data, which confidence interval would be the 95% confidence interval for p? a. (0.068, 0.082) b. (0.068, 0.078) c. (0.098, 0.112) d. (0.085, 0.096)
A students wants to estimate the proportion of professors who drive pickup trucks. She surveys 250 professors from across the country and uses the results to construct a 90% confidence interval estimate of p, the proportion of all professors who drive pickup trucks. If she were to do this with a total of 118 different sample of 250 professors, yielding 118 different 90% confidence interval estimates of p, approximately how many intervals would contain the true value of p?
Order to estimate the percentage of adults who file their taxes at least two weeks before the April 15 deadline, a 95% confidence interfull is constructed.

If two people used the same data and one person made a 90% confidence interval and the other person made a 95% confidence interval for p, which interval would be more narrow? is it; a. The 90% Confidence interval b. The 95% Confidence interval c. We cannot tell from the information alone.
It was found that in a sample of 90 teenage boys, 70% of them have received speeding tickets. What is the 90% confidence interval of the true proportion of teenage boys who have received speeding tickets? Given the above information, how many boys must be sampled to be within 2% of true proportion in a 90% confidence interval? b. If no information is given for the proportion, how many boys must be sampled?
After Texas A&M lost again to their rival, the University of Texas, in a football game, the A&M Alumni association decided to conduct a survey to see who wanted to fire the head football coach. Let p represent the proportion of all alumni who favor firing the coach. To guarantee an estimate that is within 0.05 of p at the 95% confidence level, which of the following is the smallest sample size needed? a 269 b 1436 c 385 d 601 e 421

In a statistics activity, students are asked to determine if there is a difference in the proportion of times that a spinning penny will land with tails up, and the proportion of times a spinning dime will land tails up. The students are instructed to spin the penny and the dime 30 times and record the number of times they land tails up. For one student, the penny lands tails side up 18 times, and the dime lands tails side up 20 times. Based on the 98% confidence interval, (–0.36, 0.22), is there evidence of a difference in proportions of tails side up for a penny and a dime? There is convincing evidence because the two sample proportions are different. There is not convincing evidence because the interval contains 0. There is convincing evidence because the difference in the two sample proportions is –0.07. Since this is not 0, there is a difference in the true proportions of tails up for pennies and dimes. There is not convincing evidence because the interval contains both…
