Question

Samples of size 100 from Population 1 with mean 88 and standard deviation 12 and samples of size 90 from Population 2 with mean 73 and standard deviation 15

Round your answer for the standard error to two decimal places.

standard error =

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.
