Use R to do this problem.
Make sure to store each of the answerin a chosen variable, and display the results with propertitle.
(d) Now redo all three parts by usingnormal distribution approximation, after computing the mean andstandard deviation, from the formulae given below.
µ = np and σ = sqrt(np(1-p))
Repeat steps (a), (b) and (c) using normal distribution andverify the answers obtained above.
