Testing: Ho: M = 29.3 H1:u # 29.3 Your sample consists of 32 values, with a sample mean of 29. Suppose the population standard deviation is known to be 1.41. a) Calculate the value of the test statistic, rounded to 2 decimal places. Z = -6.81 b) At a = 0.02, the rejection region is Oz 2.33 Oz > 2.05 Oz > 2.05 Oz > 2.33 c) The decision is to O Fail to reject the null hypothesis O Accept the null hypothesis O Accept the alternative hypotheis O Reject the null hypothesis
