The number of entrees purchased in a single order at a Noodles & Company restaurant has had a 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? (b-1) Calculate the t statistic. (Round answer to 2 decimal places.)
