Problem 4CQQ

Question? ?refer to the sample data in the following table (based on data from the Bureau of Labor Statistics). The table lists frequencies for randomly selected nonfatal occupation injuries arranged according to day of the week. Assume that we want to use a 0.05 significance level to test the claim that such injuries occur with equal frequency on different days of the week. D a y N u m b e r If using a 0.05 significance level to test the stated claim, find the number of degrees of freedom and the critical value.

Step 1 of 3

Solution 4CQQ Step1: Days Mon Tue Wed Thu Fri Number 23 23 21 21 19 With = 0.05 level of significance Step2: Our aim is to find the number of degrees of freedom and the critical value. Degrees of freedom can be calculated by using formula df = (r-1) Where, r = number of categories in row variable. df = (5-1) = 4 Now, We can find critical value by using the chi-square distribution table using degrees of 2 freedom 4 with 0.05 level of significance. I.e the critical value is = 9.488
