Question

Find the minimum sample size required to estimate the mean pulse rate of adult females in
order to be 90% confident that the sample mean is within 4 beats per minute (bpm) of the true
population mean, assuming that the standard deviation of the population is known to be
8.5 bpm

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.
