Only 353 of the 1,000 respondents chose the correct answer of "never." For purposes of this exercise, assume that the sample is representative of adult Americans. Is there convincing evidence that the proportion of adult Americans who can answer this question correctly is less than 0.40 (40%)? Use ? = 0.05 to test the appropriate hypotheses. (Hint: See Example 10.10.) State the appropriate null and alternative hypotheses. H0: p ≠ 0.40 versus Ha: p = 0.40 H0: p = 0.40 versus Ha: p ≠ 0.40 H0: p = 0.40 versus Ha: p < 0.40 H0: p < 0.40 versus Ha: p > 0.40 H0: p = 0.40 versus Ha: p > 0.40
