Hypothesis testing

Doctors nationally believe that 70% of a certain type of operation are successful. In a particular hospital, 42 of these operations were observed and 32 of them were successful. At a - 0.05 is this hospital's success rate different from the national average? Yes, because the test value 0.52 is in the critical region. O No, because the test value 0.52 is in the noncritical region. O No, because the test value 0.88 is in the noncritical region. O Yes, because the test value 0.88 is in the noncritical region. Find the critical values for the following values of the significance level a, sample size 77, and alternate hypothesis H. a=0.01 , n = 8, H1: M# Po O -3.499, 3.499 O -3.355, 3.355 O -2.326, 2.326 O -2.998, 2.998
