Question

You and some friends have decided to test the validity of an advertisement by a local pizza restaurant, which says it delivers to the dormitories faster than a local branch of a national chain. Both the local pizza restaurant and national chain are located across the street from your college campus. You define the variable of interest as the delivery time, in minutes, from the time the pizza is ordered to when it is delivered. You collect the data by ordering 10 pizzas from the local pizza restaurant and 10 pizzas from the national chain at different times. The hypothesis test to be performed is:

Answer 1

H₁ = The local pizza takes less time than the chain.

H₀= The local pizza takes more time than the chain.

Explanation:

Since you want to know if the advertisement by the local pizza restaurant ("It delivers to the dormitories faster than a local branch of a national chain") is true, the hypothesis to be performed is

H₁ = The local pizza takes less time than the chain.

H₀= The local pizza takes more time than the chain.
