You wish to test the following claim a significance level of α=0.02\displaystyle \alpha={0.02}.

Ho:p=0.47\displaystyle {H}_{{o}}:{p}={0.47}
Ha:p<0.47\displaystyle {H}_{{a}}:{p}<{0.47}

You obtain a sample of size n=379\displaystyle {n}={379} in which there are 152 successful observations.

  1. What is the test statistic for this sample?
