Question

I've been studying this problem and need help completing

Suppose x has a distribution with u = 30 and o = 24.
(a) If a random sample of size n = 35 is drawn, find ux, o x and P(30 sxs 32). (Round gx to two decimal
places and the probability to four decimal places.)
Hx =
ox =
P(30 s x5 32) =
(b) If a random sample of size n = 65 is drawn, find ux, o x and P(30 s x s 32). (Round ox to two decimal
places and the probability to four decimal places.)
UX =
o x=
P(30 sxs 32) =
