Question

You have sample data that leads you to believe

that the average high temperature in Oklahoma
City is 92F.
What is the alternative hypothesis, Ha, for this
situation?

u<90
u>90
u=90
u doesn’t =90

Answer 1

`\mu > 90`

Explanation:

The alternative hypothesis is an alternative hypothesis to the null, that is, in case of failing the null hypothesis, you have the alternative.

Remember, in statistics, when we want to prove a system of hypothesis, we take the null one as principa, if it fails, we have alternative hypothesis.

Now, in this case, the alternative hypothesis is
`\mu > 90`, because it the most viable response in case that the null hypothesis fails.

Answer 2

`\mu >  90`

Explanation:

I have sample data that leads me to believe that the average high temperature in Oklahoma City is 92° F.

Now, I have to find the alternative hypothesis
`H_(a)` for the situation.

So,
`\mu >  90` represents the alternate hypothesis, where
`\mu` implies the mean temperature.

Therefore, option B is correct. ( Answer )
