The number of entrees purchased in a single order at a Noodles & Company restaurant has had an historical average of 2.05 entrees per order. On a particular Saturday afternoon, a random sample of 50 Noodles orders had a mean number of entrees equal to 2.4 with a standard deviation equal to 0.82. At the 5 percent level of significance, does this sample show that the average number of entrees per order was greater than expected?(a) Choose the correct null and alternative hypotheses.a. H0: μ ≥ 2.05 vs. H1: μ < 2.05b. H0: μ ≤ 2.05 vs. H1: μ > 2.05c. H0: μ = 2.05 vs. H1: μ ≠ 2.05

A question of medical importance is whether jogging leads to a reduction in one’s pulse rate. To test this hypothesis, 8 nonjogging volunteers agreed to begin a 1-month jogging program. After the month their pulse rates were determined and compared with their earlier values. If the data are as follows, can we conclude that jogging has had an effect on the pulse rates? Subject 1 2 3 4 5 6 7 8 Pulse Rate Before 74 86 84 79 70 78 79 70 Pulse Rate After 70 85 90 110 71 80 69 74Can you conclude that jogging leads to a reduction in one's pulse rate?
