Testing: 15.1 < 15.1 Your sample consists of 46 values, with a sample mean of 14.3. Suppose the population standard deviation is known to be 2.31. a) Calculate the value of the test statistic, rounded to 2 decimal places. b) At a O o Z O O Z O Z O Z 0.02, the rejection region is > 2.33 < -2.33 or z > 2.33 > 2.05 < -2.05 or z > 2.05 < -2.33 < -2.05 c) The decision is to Reject the null hypothesis o Ihr23mins Screenshot
