Question

A population of values has a normal distribution with μ=188.5 and σ=32.8 You intend to draw a random sample of size n=204

Find P₄, which is the mean separating the bottom 4% means from the top 96% means.
P₄ (for sample means) = Round to 1 decimal place.

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.
