The number of entrees purchased in a single order at a Noodles & Company restaurant has had a historical average of 1.65 entrees per order. On a particular Saturday afternoon, a random sample of 22 Noodles orders had a mean number of entrees equal to 1.7 with a standard deviation equal to 0.9.

The number of entrees purchased in a single order at a Noodles & Company restaurant has had a historical average of 1.65 entrees
per order. On a particular Saturday afternoon, a random sample of 22 Noodles orders had a mean number of entrees equal to 1.7 with
a standard deviation equal to 0.9. 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. Hg: P2 1.65 vs. H: p<1.65
b. Hg: Us 1.65 vs. H: >1.65
c. Hạ: H = 1.65 vs. H: u# 1.65
O a

Oc
(b-1) Calculate the tstatistic. (Round your answer to 2 decimal places.)
tcale
(b-2) Find the p-value. (Round your answer to 4 decimal places.)
p-value
(c) Choose the correct conclusion.
O 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.
O 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.
