Question

a formal hypothesis test is to be conducted to test the claim that the wait times at the space mountain ride in walt disney world have a mean equal to 48 minutes. complete parts (a) through (d).
a. what is the null hypothesis, and how is it denoted?
: minute(s)
(type an integer or a decimal. do not round.)

Explanation:

In hypothesis testing, the null hypothesis ($H_0$) is a statement of no difference or no effect. Here, the claim is about the mean wait - time. The null hypothesis for a claim about a population mean ($\mu$) is a statement that the mean is equal to a specific value. Since the claim is that the mean wait - time is 48 minutes, the null hypothesis is that the population mean ($\mu$) of the wait - times is 48 minutes.

Answer:

$H_0:\mu = 48$ minute(s)
