Elementаry Prоb. аnd Stаtistics – Test 4 Shоw wоrking!     a) True or False….A larger sample size produces a longer ( wider ) confidence interval.       b) True or False….For the same random sample, when the confidence level c is reduced, the confidence interval for becomes shorter.             A sample of 10 C.E.O salaries was taken. The mean salary was $12 898 000 and the sample standard deviation was $7 719 000. Construct a 95% confidence interval for the mean salary of the population of all C.E.O’s.                           A random sample of 5792 physicians in Colorado showed that 3139 provide some charity care. Find a 99% confidence interval for the proportion of all Colorado physicians who provide some charity care.                           Interpret the confidence level in question 3.                     For the data in question 3, if you wish the margin of error to be no more than 4%, what sample size would be necessary ?                             If a 90% confidence interval for the difference in proportions contains some positive and  some negative values, what can we conclude about the relationship between p1 and p2  at the 90% confidence level ?                             Consider two independent normal distributions. A random sample of size n1=20 from the first distribution gave xbar1=12 and a random sample of size n2=25 from the second distribution gave xbar2=14. Given sigma1=3 and sigma2=4, find a 90% confidence interval for mu1 – mu2.                       A sample of 45 pro football players had an average height of 6.179ft with a sample  standard deviation of 0.366ft and a sample of 40 pro basketball players had a mean height of 6.453ft with a sample standard deviation of 0.314ft. If mu1 is the mean height for all football players and mu2 is the mean height of all basketball players, find a 90% confidence interval for mu1 – mu2.                             Interpret the confidence interval in question 8 in the context of the problem.                     In a hypothesis test, what does a p-value represent ?                 In hypothesis testing, what is: (a) A type 1 error ?         (b) A type 2 error ?         In hypothesis testing, what is Statistical Power ?                 If the p-value in a statistical test is greater than the level of significance for the test, do we reject or fail to reject H0 ? Why ?                     If the p-value for a hypothesis test with a two-sided alternative hypothesis test is 0.42, what would the p-value be for the hypothesis with a one-sided alternative hypothesis ? Why ?                   Arsenic occurs naturally in some ground water. A mean arsenic level of mu=8.0 parts per billion ( ppb ) is considered safe for agricultural use. A well in Oklahoma is tested 36 times and gave a sample mean of 7.2 ppb with s=1.9 ppb. Does this information indicate that the mean level of arsenic in this well is less than 8 ppb. Use alpha = 0.01 . Use a p-value approach.                                 Repeat question 15, only this time use a critical region approach.
