Question

A newsletter publisher believes that more than 24% of their readers own a personal computer. Is there sufficient evidence at the 0.10 level to substantiate the publisher's claim? State the null and alternative hypotheses for the above scenario.

Answer 1

Explanation:

Hello!

The newsletter publisher claims that more than 24% of their readers own a personal computer.

The parameter of interest is the proportion of readers that own a personal computer, symbolically: "p"

You can symbolize the claim of the publisher as: p > 0.24

Now remember that the null hypothesis always states the "no change" situation or the "known" situation and the researcher claim is often in the alternative hypothesis.

The null hypothesis always carries the equality sign "="

With this in consideration, the hypotheses of the newsletter publisher should be:

H₀: p ≤ 0.24

H₁: p > 0.24

I hope this helps!
