In order to test this claim, a random sample of 16 of the courier"s deliveries produced a sample mean time of 5.79 hours with a sample standard deviation of 0.28 hours. The following hypotheses were constructed: Ho: μ ≥ 6 Ha: μ < 6 Fill in Multiple Blanks The actual value of the test statistic is ______________. In your answer, show one (1) digit to the right of the decimal point, for example, 1.0, 1.2. Apply the appropriate rounding rule if necessary. The critical value of the test statistic at the 1% significance level is ______. In your answer, show one (1) digit to the right of the decimal point, for example, 1.0, 1.2. Apply the appropriate rounding rule if necessary. At the 1% significance level, we (reject, do not reject) Ho and conclude that the average delivery time (is, is not) less than 6 hours for local deliveries.
A local courier service advertises that its average delivery time is less than 6 hours for local deliveries. In order to test this claim, a random sample of 16 of the courier"s deliveries produced a sample
