please solve parts 1 and 2

1- Let X~ N (120, 81), if n = 9 then P(X > 125) = HANG 2. p(z < 1.5) = 3. Let X-N (60, 16), if n = 36 then the 92th percent of x = 4-p (X10 a) = 0.90 then a = 5. If X~ N (30,0²), if n = 10, s² = 5 then p (X < 32 ) is 6. The sample size needed so that the 95% C.I for p has length= 0.08 is
