To test the hypothesis, the following data are collected from 120 randomly selected calls placed on the teen hotline. Based on the data, is the assumption regarding the distribution of topic issues appropriate? Use alpha=.05. Give each of the following to receive full credit:  2) the appropriate test;  4) the calculation of the test statistic, and 5) your conclusion including a comparison to alpha or the critical value.     Drugs Sex Stress Education # of calls 50 37 25 8
