The number of entrees purchased in a single order at a Noodles

& Company restaurant has had an historical average of 2.1

entrees per order. On a particular Saturday afternoon, a random

sample of 28 Noodles orders had a mean number of entrees equal to

2.4 with a standard deviation equal to 0.98. 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: Î¼ â‰¥ 2.1 vs. H1: Î¼ < 2.1

b. H0: Î¼ â‰¤ 2.1 vs. H1: Î¼ > 2.1 c. H0: Î¼ = 2.1 vs. H1: Î¼ â‰ 2.1 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 0.01, we conclude that there is

evidence to indicate a significant increase in the average number

of entrees per order. Because the p-value is greater than 0.01, we

conclude that there is no evidence to indicate a significant

increase in the average number of entrees per order.
