The standard deviation of a normal population is 10. You take a sample of 25 items from this population and compute a 95% confidence interval. In order to compute the confidence interval, you will use a. the t table because the degrees of freedom will be 24. b. the t table because you have estimated the standard deviation from the sample. c. the z table because the population standard deviation is known. d. the z table because the sample size is small. e. none of the above

A statistician wishes to determine the difference between two population means. A sample of 18 items from Population #1 yields a mean of 205 with a standard deviation of 12. The sample of 15 items from Population #2 yields a mean of 190 with a standard deviation of 10. Assume that the values are normally distributed in each population. How many degrees of freedom are there for this test? a. 18 b. 14 c.15 d. 17
