I figured it out do not need answer anymore i just dont know how to delete a question. thank you

Carbon monoxide: A recent study examined the effects of carbon monoxide exposure on a group of construction workers. The following table presents the numbers of workers who reported various symptoms, along with the shift (morning, evening, or night) that they worked. Morning Influenza 18 Headache 27 Weakness Shortness of Breath Shift Evening 12 22 13 11 Night 12 . . 11 (a) Compute the expected frequencies under the null hypothesis. (b) Compute the value of the chi-square statistic. (c) How many degrees of freedom are there? (d) Test the hypothesis of independence. Use the -6.8 level of significance. What do you conclude? Part 1 of 10 (a) Compute the expected frequencies under the null hypothesis. Compute the expected frequencies of the workers with influenza, Round the answers to at least three decimal places. Morning Night Evening 12 Influenza Cort Anew Morning IK 191 Influenza Evening 15516 Night 293 Part 1/10 Part 2 of 10 Compute the expected frequencies of the workers with headache. Round the answers to at least three decimal places. Morning Evening Night Headache Carbon monoxide: A recent study examined the effects of carbon monoxide exposure on a group of construction workers.
