2. You are conducting a study to see if the proportion of men over 50 who regularly have their prostate examined is significantly different from 0.25. You use a significance level of ?=0.005 H0:p=0.25H0:p=0.25 H1:p?0.25H1:p?0.25 You obtain a sample of size n=651 in which there are 177 successes. 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 =

3. In a recent Super Bowl, a TV network predicted that 27 % of the audience would express an interest in seeing one of its forthcoming television shows. The network ran commercials for these shows during the Super Bowl. The day after the Super Bowl, and Advertising Group sampled 148 people who saw the commercials and found that 34 of them said they would watch one of the television shows. Suppose you are have the following null and alternative hypotheses for a test you are running: H0:p=0.27 Ha:p>0.27 Calculate the test statistic, rounded to 3 decimal places
