Question

5. A researcher investigating whether joggers are less likely to get colds than people who do not jog found a P-value of 3%. What does that mean? (Hint: it would help if you write the null and alternative hypotheses and pick some confidence level to compare the p-value to).

Please show all work. Typed work only. no handwritten.

Answer 1

Solution:

Given that,

  A researcher investigating whether joggers are less likely to get colds than people who do not jog found a P-value of 3%

H 0:

Joggers and Non - Joggers are equally likely to get cold

H 1:

Joggers and Non -Joggers are not equally likely to get cold

Let us consider ,

Alpha = 5 %

It means  hypothesis at 95 % level of significance

At this LoS ,

If P- value = 3 %

P< Alpha

We can dismiss the null and tell that Joggers and Non- Joggers are not equally likely to get cold

However, the interpretation part means that

At 3 % level ,

we can dismiss the null hypothesis
