T You wish to test the following claim (Ha) at a significance level of a = 0.01. Ho: u = 70.1 Ha: u # 70.1 You believe the population is normally distributed, but you do not know the standard deviation. You obtain the following sample of data: data 73.9 78.9 75.6 79.4 72.4 83 102.2 87.3 77.1 73.2 104.1 78.3 What is the critical value for this test? (Report answer accurate to three decimal places.) critical value = + 2.72 x What is the test statistic for this sample? (Report answer accurate to three decimal places.) test statistic = 3.91 The test statistic is... O in the critical region not in the critical region This test statistic leads to a decision to
