Question

For a population with a mean equal to200and a standard deviation equal to 35, calculate the standard error of the mean for the following sample sizes.

a) 15

b)50

c)85

Question content area bottom

Part 1

a) The standard error of the mean for a sample size of 15 is

(Round to two decimal places as needed.)

Part 2

b) The standard error of the mean for a sample size of 50 is

(Round to two decimal places as needed.)

Part 3

c) The standard error of the mean for a sample size of 85 is

Definition Definition Number of subjects or observations included in a study. A large sample size typically provides more reliable results and better representation of the population. As sample size and width of confidence interval are inversely related, if the sample size is increased, the width of the confidence interval decreases.
