You may need to use the appropriate appendix table or technology to answer this question. A student believes that no more than 20% (i.e., s 20%) of the students who finish a statistics course get an A. A random sample of 100 students was taken. Twenty-three percent of the students in the sample received 'A's. (a) State the null and alternative hypotheses. (Enter != for = as needed.) H₂: H₂: (b) Using the critical value approach, test the hypotheses at the 1% level of significance. Compute the test statistic. 0.04 Determine the critical value(s) for this test.
