Results of the taste test indicate that 52 of 100 individuals prefer Brand A. Complete parts a through c (a) Conduct a hypothesis test (preferably using technology) Ho: p-Po versus H p Po for po 0.41, 0.42, 0.43,.... 0.61, 0.62, 0.63 at the a 0.05 level of significance. For which values of po do you not reject the null hypothesis? What do each of the values of Po represent? and inclusively. Do not reject the null hypothesis for the values of po between (Type integers or decimals as needed.)
