(a) Null hypothesis: The time to order and deliver a pizza to his customers at Jimbo's pizza is 48 minutes

Alternate hypothesis: The time to order and deliver a pizza to his customers at Jimbo's pizza is less than 48 minutes

(b) To make a type I error means that the null hypothesis is rejected when it is true

(c) To make a type II error means that the null hypothesis is accepted when it is false

Step-by-step explanation:

(a) A null hypothesis is a statement deduced from a population parameter which would be tested to be true or false.

An alternate hypothesis is a statement deduced a population parameter that negates the null hypothesis.

(b) Type I error means rejecting the null hypothesis when it is true

(c) Type II error means accepting the null hypothesis when it is false
