Question: Lynette has owned a small pizzeria for the last five years. Recently, she has gotten accustomed to paying $33 for a bag of wheat flour to make her pizzas (which is a much higher price than last year). However, she believes there is another price spike happening. To ensure that she is not getting ripped off by her current supplier, she takes
a simple random sample of 10 other suppliers and finds out the price they charge for a bag of wheat flour, given below:
45, 47, 46, 50, 44, 48, 48, 49, 50, 51
You can assume that the data is normally distributed. At the .05 level of significance, does Lynette have evidence that the mean price for a bag of wheat flour is now higher than $33?
