A data set includes data from student evaluations of courses. The summary statistics aren 86, x = 3.82, s = 0.52. Use a 0.01 significance level to test the claim that the population of student course evaluations has amean equal to 4.00. Assume that a simple random sample has been selected. Identify the null and alternative hypotheses, test statistic, P-value, and state the final conclusion that addresses the original claim,What are the null and alternative hypotheses?O A.

This is because nausea is common for people who have the flu. From past studies you know that about 33% of people who get the flu experience nausea. You collected data on 2371 patients who were taking Tamiflu to relieve symtoms of the flu, and found that 841 experienced nausea. Use a 0.01 significance level to test the claim that the percentage of people who take Tamiflu for the relief of flu symtoms and experience nausea is greater than 33%. *.** ▸ Ezra Mill X HH Chief Be X V H₁: ?
