Question

find the minimum sample size n needed to estimate μ for the given values of c,σ,and E.

c=0.95,

σ=5.5,

and

E=1

Assume that a preliminary sample has at least 30 members.

n= (round up to the nearest whole number)

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.
