can you help me with this question please, these pictures are both part of the same problem

In the hypothesis testing forum, one student wrote: "I'm interested in whether the number of pets and the hours worked (at a job) are related (maybe because of time management?)." I sorted the class survey results to get the following information: no pets 1 pet 2+ pets no job 15 13 1-20 hrs per week 13 24 21+ hrs per week 10 10 26 a. How many students total were surveyed? The student continued: "My null hypothesis would be that number of pets and hours worked are independent, and my alternative hypothesis would be that those two variables (number of pets and hours worked) are dependent." The table below shows what we would see if hours worked were independent (values rounded to the nearest tenth). This was done on the calculator, however, we also learned how to do this by hand. no pets 1 pet 2+ pets no job 10.6 7.8 17.6 1-20 hrs per week 13.8 10.2 23 21+ hrs per week 13.6 10 22.5 b. explain how we could find the first entry (10.6) in matrix B by hand. C. Look at the two matrices. What is your gut instinct? Are these two matrices pretty different or pretty similar? There is no wrong answer, but back up your decision with some numerical observations.Perform the Chi Square Test: Enter matrix A into your calculator by going to 2nd Matrix>>Edit 1:A and enter the first matrix. You do not need to enter the 2nd matrix. Stat >Tests C:X2 - Test make sure Observed is Matrix A and Expected is Matrix B (this should be the default. If you need to change the name of the matrix, you can press 2nd matrix and then choose A or B and press enter.) d. The value of the test statistic is (round to 2 decimal places) X2 = e. The p value is (round to 2 decimal places) =
