Question

In a 95% confidence interval. i 1-0.0s is called the confidence coefficient. A) True lB) False If a 95% confidence interval on the mean has a lower limit of 10 and an upper limit that 95% of the time the true value of the mean is between 10 and 15. ) True B) False For a fixed value of the standard deviation and a fixed sample size, a confidence inte population mean will get longer as the level of confidence increases from 95% to 999 A) True B) False For a fixed value of the standard deviation, a 95% confidence interval on the populati shorter if the sample size increases. A) True B)False the upper one-sided 95% confidence bound of the mean of a normal distribution will al than the upper bound on the mean from a two-sided 95% confidence interval. Question 5 options A) True B) False If S? is the sample variance of a random sample of size n from a normal distribution, the has a chi-square distribution with n - 1 degrees of freedom A) True B) False

CI on the variance of a normal distribution makes use of the t distribution A) True B) False The normal approximation to the binomial can be used to construct a CI on a population pr CA) True B) False The prediction Interval for a fuiture obuern-ation from a sormal distribution will always be long CI on the mean of the nonnal distribution C A) True B) False A tolerance interval is a statistical interval that captures a future value of a normal random variab CA) True B) False
