    Answer:

    The evidence is not sufficient at the 0.02 level of significance to reject the claim that the percentage is 30%.

    Step-by-step explanation:

    Let’s first state the null and alternative hypotheses for this research;

    H0: p = 0.30

    Ha: p ≠ 0.30

    Now, since the bull hypothesis is the claim and he fails to reject the null hypothesis from the research, we will conclude that;

    The evidence is not sufficient at the 0.02 level of significance to reject the claim that the percentage is 30%.
