Assume that the red blood cell counts of women are normally distributed with a mean of 4.577 million cells per microliter and a standard deviation of 0.382 million cells per microliter. find the value closest to the probability that a randomly selected woman has a red blood cell count above the normal range of 4.2 to 5.4 million cells per microliter. round to four decimal places.

0.8231

Step-by-step explanation:

Given: Mean :

Standard deviation :

The formula to calculate z is given by :-

For x=  4.2

The P Value =

For x= 5.4

The P Value =

Hence, the probability that a randomly selected woman has a red blood cell count above the normal range of 4.2 to 5.4 million cells per microliter=0.8231

the correct answer is you spend $55.78 more in a brand store that buy ing in a normal store.

step-by-step explanation:

brand = spend   $ 135.85 total

store = spend $80.07 total
