Question

You are conducting a study to see if the proportion of women over 40 who regularly have mammograms is significantly less than 0.17. You use a significance level of α=0.002

H0:p=0.17
H1:p<0.17

You obtain a sample of size n=625 in which there are 90 successes.

What is the test statistic for this sample? (Report answer accurate to three decimal places.)

What is the p-value for this sample? (Report answer accurate to four decimal places.)

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.
