Question

You wish to test the following claim (HaHa) at a significance level of α=0.05

Ho:p=0.17
Ha:p<0.17

You obtain a sample of size n=287 in which there are 30 successful observations.

Determine the test statistic formula for this test.

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

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

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.
