I really need help with question 3 parts a, b, c, and d. But feel free to answer all

2). In order to estimate the proportion of taxpayers who underpay Federal Income Tax, a sample of 1000 tax filings is inspected, and it is found that in 641 cases there were underpayments. Compute 99% confidence intervals for the proportion, t, of taxpayers who underpay. For the Wald method give each interval in both forms (estimate error margin), and (Lower, Upper). For the scores method use binom.test in R (i). Wald method: ; (ii). Scores method: + 3). Use the data in problem 2 to test Ho: 1 = .6 vs H: 15.6. Find: (a). z-statistic (Score Test) = ;P-value (Score Test)=. (b). Z-statistic (Wald Test) = ;P-value (Wald Test)= (c). x statistic (L-R test) = ;P-value (L-R Test)=. (d). Use binom.test in R to obtain to exact P-value. P-value = 2).
