The mean incubation time for a type of fertilized egg kept at a certain temperature is 25 days. suppose that the incubation times are approximately normally distributed with a standard deviation of 1 day. complete parts (a) through(e) below.

(a) draw a normal model that describes egg incubation times of these fertilized eggs.

(b) find and interpret the probability that a randomly selected fertilized egg hatches in less than 23 days.

the probability that a randomly selected fertilized egg hatches in less than 23 days is (round to four decimal places asneeded.)

Step-by-step explanation:

Given that the  mean incubation time for a type of fertilized egg kept at a certain temperature is 25 days.

Let X be the incubation time for a type of fertilized egg kept at a certain temperature is 25 days.

X is N(25, 1)

a) Normal curve is in the attached file

b) the probability that a randomly selected fertilized egg hatches in less than 23 days

=

we convert x into Z score and use std normal distn table to find probability

i.e. we can say only 2.5% proportion will hatch in less than 23 days.
