The number of entrees purchased in a single order at a Noodles & Company restaurant has had an historical average of 1.60 entrees per order. On a particular Saturday afternoon, a random sample of 40 Noodles orders had a mean number of entrees equal to 1.80 with a standard deviation equal to 1.11. 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 ≥ 1.6 vs. H1: μ < 1.6 b. H0: μ ≤ 1.6 vs. H1: μ > 1.6 c. H0: μ = 1.6 vs. H1: μ ≠ 1.6 a b c (b-1) Calculate the t statistic. (Round your answer to 2 decimal places.) tcalc (b-2) Find the p-value. (Round your answer to 4 decimal places.) p-value (c) Choose the correct conclusion. Because the p-value is less than .05, we conclude that there has been a significant increase in the average number of entrees per order. Because the p-value is greater than .05, we conclude that there is no evidence to indicate a significant increase in the average number of entrees per order.
