Question 1179460: The mean incubation time for a type of fertilized egg kept at a certain temperature is 24 days. Suppose that the incubation times are approximately normally distributed with a standard deviation of 2 days.
The probability that a randomly selected fertilized egg hatches between 20
and 24 days is?

Hi
Distribution: approximately normal with µ = 24 and σ = 2
Using TI or similarly an inexpensive calculator like an Casio fx-115 ES plus
SELECT ONE:
P( 20 < x < 24) = normalcdf(20,24,24,2) = .4772

Wish You the Best in your Studies.
