6 A simple random sample of 28 wait times while pumping gas at a gas station has a standard deviation of 20 seconds The test statistic for the random sample is 22 314 when found to test a claim that the standard deviation for all wait times while pumping gas at a gas station is less than 22 seconds Using a 0 05 significance level find the critical value and state the initial conclusion 1 point 016 151 because the test statistic is greater than the critical value there is not sufficient evidence to support the claim that the standard deviation for all wait times while pumping gas at a gas station is less than 22 seconds 16 151 because the test statistic is less than the critical value the test supports the claim that the standard deviation for all wait times while pumping gas at a gas station is less than 22 seconds 040 113 because the test statistic is less than the critical value the test fails to reject the claim that the standard deviation for all wait times while pumping gas at a gas station is less than 22 seconds 40 113 because the test statistic is greater than the critical value there is not sufficient evidence to support the claim that the standard deviation for all wait times while pumping gas at a gas station is less than 22 seconds
