A soccer ball manufacturer wants to estimate the mean circumference of soccer balls within 0.18 inch.(a) Determine the minimum sample size required to construct a 99% confidence interval for the population mean. Assume the population standarddeviation is 0.6 inch.(b) The sample mean is 27.7 inches. With a sample size of 84, a 99% level of confidence, and a population standard deviation of 0.6 inch, does it seempossible that the population mean could be less than 27.8 inches? Explain.Click here to view page 1 of the Standard Normal Table.

Are people more confident in their answers when the answer is actually correct than when it is not? A study was done on medical students' confidence and the accuracy of their responses. Participants categorized their confidence levels using either "sure", "feeling lucky" or "no clue". Define the following events C= event that a response is correct S= event that confidence level is "sure" L = event that confidence level is "feeling lucky" N = event that confidence level is "no clue" P(S) = 0.442 P(L) = 0.422 P(N) = 0.136 P(C|S) = 0.783 P(C | L) = 0.498 P(C| N) = 0.320 Not C total 346 96 442 L 210 212 442 N 44 92 136 total 600 400 1000 1.

Assume that a sample is used to estimate a population mean. Find the 90% confidence interval for a smaple of size 46 with a mean of 68.5 and a standard deviation of 6.6. Enter the answer as an open-interval (parentheses) accurate to one decimal place (because the sample statistics are reported accurate to one decimal place).
