Question

It is reported in USA Today that the average flight cost nationwide is $445.99. You have never paid close to that amount and you want to perform a hypothesis test that the true average is actually greater than $445.99. What are the appropriate hypotheses for this test

Answer 1

Answer:

$H_0$ : $\mu \leq 445.99$

$H_a$ : $\mu > 445.99$

Step-by-step explanation:

It is given the average cost of the flight nationwide is $ 445.99

I wanted to $\text{perform the hypothesis test}$ to determine that the true average is greater than $ 445.99

Let the hypothesis that the true average is actually greater than $445.99

Therefore,

the $\text{null hypothesis}$ for the test is :

$H_0$ : $\mu \leq 445.99$

And the alternate hypothesis is :

$H_a$ : $\mu > 445.99$
