A blind taste test is conducted to determine which of two colas, Brand A or Brand B, individuals prefer. Individuals are randomly asked to drink one of the two typ cola first, followed by the other cola, and then asked to disclose the drink they prefer. Results of the taste test indicate that 57 of 100 individuals prefer Brand A. Complete parts a through c. (a) Conduct a hypothesis test (preferably using technology) Ho: p = Po versus H1: p#Po for po = 0.46, 0.47, 0.48, ..., 0.66, 0.67, 0.68 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? Do not reject the null hypothesis for the values of po between and , inclusively.
