Question

Which of the following is NOT correct? The standard error of a statistic describes a. The standard deviation of the sampling distribution of that statistic. b. The standard deviation of the sample data measurements. c. How close that statistic falls to the parameter that it estimates. d. The variability in the values of the statistic for repealed random samples of size n The coach of UWW men's basketball team records the resting heart rates of the 15 team members You should not trust a confidence interval for the mean resting heart rate of all male students at UWW based on this data because: a. With only 15 observations, the margin of error will be large. b. Heart rates may not have a Normal distribution c. The members of the basketball team can't be considered a random sample of all students d. You don't know the standard deviation Based on responses of 1467 subjects in a General Social Survey, a 95% confidence interval for the mean number of close friends equal (6.8,8 0). Which TWO of the following interpretations are correct? a. We can be 95 degree confident that X is between 6.8 and 8.0. b. We can be 95 degree confident that p is between 6.8 and 8 0. c. Ninety-five percent of the values of X-Number of close friends (for this sample) are between 6.S and 8.0.
