In a recent poll of 745 randomly selected adults, 588 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.

Voters commonly condemn politicians for being insincere, but politicians often must disguise their true feelings when they make public statements. if they expressed their honest views—about, say, their party's policies—then achieving politically necessary compromises would be much more difficult. clearly, the very insincerity that people decry shows that our government is functioning well. which of the following, if true, most seriously undermines this reasoning? (a) achieving political compromises is not all that is necessary for the proper functioning of a government. (b) some political compromises are not in the best long-term interest of the government. (c) voters often judge politicians by criteria other than the sincerity with which they express their views. (d) a political party's policies could turn out to be detrimental to the functioning of a government. (e) some of the public statements made by politicians about their party's policies could in fact be sincere.
