a)
for normal distribution z score =(X-μ)/σ | |
here mean= μ= | 157 |
std deviation =σ= | 3.0000 |
sample size =n= | 60 |
std error=σx̅=σ/√n= | 0.3873 |
probability = | P(X<156.2) | = | P(Z<-2.07)= | 0.0192 |
(try 0.0194 if this comes wrong)
b)
probability = | P(X<156.2) | = | P(Z<-9.81)= | 0.0000 |
c)
probability = | P(X<156.2) | = | P(Z<-4.43)= | 0.0000 |
