A2003 study of dreaming found that out of a random sample of 106 people, 80 reported dreaming in color. however, the rate of reported dreaming in color that was established in the 1940s was 0.21. check to see whether the conditions for using a one-proportion z-test are met assuming the researcher wanted to test to see if the proportion dreaming in color had changed since the 1940s.
1. what is the normal approximation method appropriate for this test? 2. compute appropriate test statistic.3. at a 0.10 level of significance, what are the critical values for the test.4. what is the appropriate decision and conclude for the test at 0.10 level of significance (fail to reject, reject ha)5. would your conclusion change if the test were to be conducted as an upper tailed test? why or why not supporting your answer using the p-value approach.
