Question 1162059: In a survey of a company, mean salary of employees is 29, 321 with SD og 2, 120 Consider the sample of 100 employees and find the probabilityt that their mean salary will be less than 29, 000? Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! I am assuming the population has a mean of $29321 with sd 2120
z=(x bar-mean)/sd
z<(29000-29321)/2120/sqrt(100)
<-321*10/2120
<-1.51
that probability is 0.0655
