The number of entrees purchased in a single order at a Noodles & Company restaurant has had an historical average of 1.35 entrees per order. On a particular Saturday afternoon, a random sample of 26 Noodles orders had a mean number of entrees equal to 1.4 with a standard deviation equal to 0.7. At the 1 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 ≥ 1.35 vs. H1: μ < 1.35 b. H0: μ ≤ 1.35 vs. H1: μ > 1.35 c. H0: μ = 1.35 vs. H1: μ ≠ 1.35 a b c (b-1)
