A2003 study of dreaming found that out of a random sample of 113 people, 35 reported dreaming in color. however, the proportion reported dreaming in color that was established in the 1940s was 0.25. the researcher wants to determine if the proportion of individuals that dream in color has changed since the 1940s. use 0.10 level of significance.

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.
