A longitudinal study conducted among black women in the United States investigated the relationship between attendance at religious services and all-cause mortality. The information is presented in table 6 below. Table 6. Frequency of attendance at religious services \table[[\table[[Attendance at religious],[services]],No. of cases,Person-years of follow up],[Never,149,247,713],[

time per week,347,72,992],[

times per month,250,50,914],[1 time per week,371,73,719],[Several times per week,276,47,607]] 2 a. Calculate the overall incidence rate ratio and interpret your results b. Calculate the exposure-specific incidence rate ratios and indicate whether there is evidence of an exposure-response relation c. Indicate the possible cause of exposure misclassification in this study d. With explanation indicate the type of exposure misclassification and mention the direction of bias? The data was stratified by smoking status with the information presented in table 5 below Table 7. Smoking status of study participants \table[[\table[[Attendance at],[religious services]],Smoker,Never smoker],[,No. of cases,\table[[Person-years],[of follow up]],No. of cases,\table[[Person-years],[of follow up]]],[Never,88,146,300,61,101,413],[Yes,846,166,774,398,78,458]] e. Calculate the stratum-specific incidence rate ratios f. Based on your answers in (e), is there evidence of confounding by smoking status of mothers? Explain briefly
