Question

A population has a mean of

1398.25

and standard deviation of

246.85

A random sample of size n =

is selected from this population.

the probability that the sample mean exceeds 1425 is,

a	0.1534
b	0.1632
c	0.1736
d	0.1847

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.
