According to a survey, 85% of American adults eat salad at least once a week. A nutritionist suspects that the percentage is higher than this. She conducts a survey of 200 American adults and finds that 171 of them eat salad at least once a week. Conduct the appropriate test that addresses the nutritionist's suspicion. Use an a = 0.05 level of significance. State the null and alternative hypothesis: What parameter are we testing? Ho: H₁: Assumptions: SRS, n < 0.05N, npo (1 - po) By hand, test statistic is (Round to 5 decimals): P-value. Round to 4 decimals: Conclusion: There is (enter sufficient or insufficient) evidence at the a = 0.05 level of significance to conclude that the percentage of adult Americans that eat salad at least once a week is ("equal to" or "higher than" or "less than" or "not equal to") 85%.
