Question

You wish to test the following claim (HaHa) at a significance level of α=0.002

Ho:p=0.72

Ha:p<0.72

You obtain a sample of size n=631n=631 in which there are 424 successful observations.

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 three 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.
