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

`H_0` :
`\mu \leq 445.99`

`H_a` :
`\mu > 445.99`

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`
