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.
Answer:
Null Hypothesis H₀ : P = 0.68
Alternative Hypothesis H₁ : P ≠ 0.68
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
