There are three random variables: X ~ Normal with mean = 60 and Standard deviation = 35 Z ~ Normal Standard W ~ t(18)df Calculate in R, the following: 1) P(X>66) = Answer 2) Find "A", such that: P(X Then A = Answer 3) P(Z>-1.54) = Response 4) Find "B", such that: P(W>B) = 0.25 ==> Then B= Answer USE R STUDIOS. DO NOT ROUND DECIMALS.
