A newsletter publisher believes that 68% of their readers own a Rolls Royce. Is there sufficient evidence at the 0.05 level to refute the publisher's claim

This question is not complete, the complete question is;

A newsletter publisher believes that 68% of their readers own a Rolls Royce. Is there sufficient evidence at the 0.05 level to refute the publisher's claim

State the null and alternative hypotheses for the above scenario.

Null Hypothesis            H₀ : P = 0.68  

Alternative Hypothesis H₁ : P ≠ 0.68  

Step-by-step explanation:

Given that;

A newsletter publisher believes that 68% of their readers own a Rolls Royce

so

proportion of readers = 68% = 68/100 = 0.68

Level of significance ∝ = 0.05

Now the Null and Alternative Hypothesis for this case will be;

Null Hypothesis            H₀ : P = 0.68  

Alternative Hypothesis H₁ : P ≠ 0.68  

.
