Definition of polynomial ring
Given a ring R, the polynomial ring is defined as
R[x] ={k=0nakxk:n0, akR for  k{0,1,,n}}.
However, it is not usually specified what x is. In order for multiplication to make sense, I guess it has to be an element in R at least. But is R[x] the set of all functions P:RR,given by  xk=0nakxk, or the set of those functions evaluated at x?
Sometimes R is required to be commutative. Does that make any difference for R[x]?

Find the probability that a single randomly selected value is between 119.8 and 121.2.
P(119.8 < X < 121.2)

 

Find the probability that a sample of size n=149n=149 is randomly selected with a mean between 119.8 and 121.2.
P(119.8 < M < 121.2)
