Question

Less than 75% of workers got their job through internet resume sites. A researcher thinks it has increased.

Express the null and alternative hypotheses in symbolic form for this claim. For example, if you have 35%, enter it as 0.35.
H0: p H1: p
Use the following codes to enter the following symbols: ? enter >= ? enter <= ? enter ! =

Answer 1

H0 : p = 0.75 against H1: p > 0.75 One tailed test.

Explanation:

We state our null and alternative hypotheses as

H0 : p = 0.75 against H1: p > 0.75 One tailed test.

In this case H0 is not defined as p≤ 0.75 because the acceptance and rejection regions cannot be set up. Therefore we take the exact value of H0 : p= 0.75.

The claim is that the probability of the workers getting their job through the internet is greater than 75% or 0.75.

As H0 is supposed to be less than we choose H1 to be greater than equality.
