The large population of a measured variable has a mean value of 23.0 and a standard deviation of 1.0. What percentage of the population falls between (a) 22 and 24? (b) 22.5 and 23.5? (c) 21 and 25? (d) 21 and 23?Explanation / Answer
2 Solution:
We know that normal distribution fuction
Z(P) = (Xm - X)/S.D.
Where
Z(P) = Probability Fuction
Xm = Mean value
X = Actual value
S.D. = standard Deviation
(A)
Z(P) = {23-(22+24)/2}/1
= 0
0%
Similar way we can find
(B) Z(P) = 50%
(C) Z(P) =50%
(D) Z(P)= 68%
