    Answer:

    Step-by-step 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!
