Question 1091320: assume that red blood cell counts of women are normally distributed with a mean of 4.342 and a standard deviation of 0.501
24 women are randomly selected, find the probability that the mean of their red blood cell count is less than 4.562 Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! z value =(x bar-mean)/sd/sqrt(n)
<(4.562-4.342)/0.501/sqrt(24)
<0.220*sqrt(24)/0.501
<2.15
probability is 0.9842
