Question

A newsletter publisher believes that over 64%64% of their readers own a Rolls Royce. For marketing purposes, a potential advertiser wants to confirm this claim. After performing a test at the 0.010.01 level of significance, the advertiser decides to reject the null hypothesis. What is the conclusion regarding the publisher's claim?

Answer 1

Explanation:

Hello!

The publisher statement is that "64% of his readers own a Rolls Royce"

The parameter in this hypothesis is the population proportion, the hypothesis used for the test are:

H₀: ρ = 0.64

H₁: ρ ≠ 0.64

If at α: 0.10 the adviser rejected the null hypothesis, this means that there is no significant evidence to support the publisher's statement. In other words, 64% of the readers do not own a Rolls Roys.

I hope it helps!
