Below is the data of 415 work teams selected at random. Use the .05 significance level. 1. What are the null an alternative hypotheses? 2. For the first cell in the table calculate the expected value, E1,1. (First cell in the first column) 3.for the first cell in the table caluculate chi-square,X2, amount?4. Now compute X2, the test statistic for the entire table? 5. What is the critical value? 6. Do you accept or reject the null hypotheses? 7. Calculate Cramers V?
