Question 1a has already been answered. I need help for parts b to f.

1. Exposure to radiation is one of the many elements that comes along with mining phosphate. In a study, the incidence of cancer among phosphate mine workers and their exposure to radiation was investigated. Cancer incidence was recorded among a sample of 65 phosphate mine workers who had 0-29 working level months (WLM) of exposure, a sample of 50 phosphate mine workers who had 30-89 WLM of exposure, and a sample of 80 phosphate mine workers who had 90-120 WLM of exposure. The number of cancer incidences for each group are presented in Table 1.\" Suppose we want to answer the following question: (1) Test, at the 5% level of signicance, whether cancer incidence rates differ between the three levels of radiation among phosphate mine workers. Table 1: Two-way Table of Counts (a) Use SPSS to produce the information needed to perform the hypothesis test in part (i) and then fill in the missing information in Table 2. Table 2 Chi-Square Tests Asymptotic Significance Value df (2-sided) Pearson Chi-Square 1023 2 950 Likelihood Ratio 102 2 950 N of Valid Cases 195 a. 0 cells (0.0%) have expected count less than 5. The minimum expected count is 17.69. (b) For the test in part (i), how many degrees of freedom does the distribution of the test statistic have? (c) What is the value of the observed test statistic associated with the test in part (i)? (d) What is the p-value associated with the test in part (i)?(e) At the 5% level of significance, does the p-value support the claim that cancer incidence rates differ between the three levels of radiation among phosphate mine workers? Explain. (f) Is the requirement that the expected frequency in each cell is 5 or greater satisfied? Explain.2. Some scientists believe that the presence of antibody to milk protein lowers the chance of survival after a heart attack. To explore this belief, a medical team took blood specimens from 300 male heart-attack patients and tested them for the presence of the antibody. The patients were then followed to determine Whether they lived for 6 months following their heart attack. The results are presented in Table 3.5 Table 3: Two-way Table of Counts Antibody to Milk Protein (a) Test, at the 5% level of signicance, Whether there is an association between the pres- ence of antibody to milk protein and survival after a heart attack.
