Question

In a recent poll of 750 randomly selected adults, 586 said that it is morally wrong to not report all income on tax returns. Use a 0.05 significance level to test the claim that 70% of adults say that it is morally wrong to not report all income on tax returns. Identify the null hypothesis, alternative hypothesis, test statistic, P-value, conclusion about the null hypothesis, and final conclusion that addresses the original claim. Use the P-value method. Use the normal distribution as an approximation of the binomial distribution. Identify the correct null and alternative hypotheses. Choose the correct answer below. A. H_0: p = 0.7 H_1: p > 0.7 B. H_0: p = 0.7 H_1: p notequalto 0.7 C. H_0: p = 0.7 H_1: p 0.3 F. H_0: p = 0.3 H_1: p

Explanation / Answer

a) option B is correct

b) Sample proportion = 586/750 = 0.781

z = (0.781-0.7)/Sqrt(0.7*0.3/750) = 4.86

P value = 0.0000

Reject H0. There is not sufficient evidence to warrant rejection of
