when the advertiser failed to reject the null hypothesis it means that the belief of the newsletter publisher that ess than 26% of their readers own a Rolls Royce is not supported by statistical evidence at 10% significance level.

Step-by-step explanation:

given that a newsletter publisher believes that less than 26% of their readers own a Rolls Royce.

H0: p = 0.26

Ha: p <0.26

when the advertiser failed to reject the null hypothesis it means that the belief of the newsletter publisher that ess than 26% of their readers own a Rolls Royce is not supported by statistical evidence at 10% significance level.
