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 types of cola first, followed by theother cola, and then asked to disclose the drink they prefer. Results of the taste test indicate that 43 of 100 individuals prefer Brand A. Complete parts a through c.Do not reject the null hypothesis for the values of po between 0.34 and 0.52 , inclusively.(Type integers or decimals as needed.)(b) Construct a 95% confidence interval for the proportion of individuals who prefer Brand A.The lower bound isThe upper bound is(Round to three decimal places as needed.) (c) Suppose you changed the level of significance in conducting the hypothesis test to a = 0.01. What would happen to the range of values for Po for which the nullhypothesis is not rejected? Why does this make sense? Choose the correct answer below.O A. The range of values would decrease because the corresponding confidence interval would decrease in size.O B. The range of values would increase because the corresponding confidence interval would decrease in size.OC. The range of values would decrease because the corresponding confidence interval would increase in size.D. The range of values would increase because the corresponding confidence interval would increase in size.
