A government Bureau claims that more than 50% of U.S. tax returns were filed electronically last year. A random sample of 150 tax returns for last year contained 86 that were filed electronically. Test the Bureau's claim at a 5% level of significance. What is your conclusion? Report the p-value for this test. A) Sample size n 150 x-86 H0: P <0.50 H1: P>0.50 B) p- x/150-0.57333 (sample proportion) C) SD 0.040825 D)z- 7300-23 -1.80 0.57333-0.5 E) level of significance 0.05 Critical value z < 1.64 F) the test statistic is greater than critical value we reject null hypothesis
