Anna is examining prices and wondering where she sits relative to competitors based on

when she is open. She only opens for lunch. She does not open for breakfast or dinner. She thinks that some restaurants charge different prices based on how oﬁen they are open

during the day (e.g., some open for lunch and dinner), signalling (cg, a higher price may

signal a certain level of quality) and a host of reasons relating to costs etc. Given a restaurant could open upon three occasions during the day, there are up to seven

combinations (23-1) of whether a restaurant serves breakfast, lunch, arid/or dinner. In this question you are asked to calculate and further consider suitable summary statistics for

the price of each of these combinations of opening times. To start, calculate the mean price,

standard deviation in prices, and number of restaurants (i.e., frequency) for each of the seven

combinations. To help Anna ﬁirther determine prices being charged by her competitors, you are asked to

construct a conﬁdence interval describing the average price of restaurants in each of the

seven categories.
