Answer:
90
Step-by-step explanation:
A meteorologist claims that the average daily high temperature in Oklahoma City is 90°F
Let µ represent the average daily high temperature, in °F, in Oklahoma City during the summer.
Null Hypothesis definition: A null hypothesis is a hypothesis that says there is no statistical significance between the two variables in the hypothesis.
So, null hypothesis [tex]H_0=90[/tex]
Hence the null hypothesis, [tex]H_0[/tex], for this situation is 90.
Considering the situation described, the null hypothesis is given as:
[tex]H_0: \mu = 90[/tex].
What are the hypothesis tested?
At the null hypothesis, it is tested if the meteorologist claim is correct, that is, the temperature is of 90°F, hence:
[tex]H_0: \mu = 90[/tex].
At the alternative hypothesis, it is tested if he is incorrect, that is, the temperature is different of 90ºF, hence:
[tex]H_1: \mu \neq 90[/tex].
