A simple random of size n = 64 is obtained from a population with Mu = 70 and Sigma = 16
What is P( x (less than equal to) 65.7 )
What is P( 69 < x < 74.4 )
Please show your work with the given numbers
Solution
Sample size n =64
Population mean mu=70
Standard deviation sigma =16
Sigma(Xbar) =sigma/sqrt(n) =16/sqrt(64)=16/8=2
Let Z =(Xbar
