Answer:
1. 45
2. 24
3. 32
Step-by-step explanation:
One
Ashley= 3/4 * Steve
Ashley= 3/4 * 60
Ashley = 180/4
Ashley = 45
Two
60% of 40
60/100 * 40
2400/100 = 24
Three
40% 80 = 40/100 * 80 = 3200 / 100 = 32
Using the normal distribution, we have that:
a) The sketch of the situation is given at the end of this answer.
b) The probability is:

In a normal distribution with mean and standard deviation , the z-score of a measure X is given by:

- It measures how many standard deviations the measure is from the mean.
- After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.
In this problem:
- Mean of 4.1 years, thus
. - Standard deviation of 1.3 years, thus
.
Item a:
The part between 2.8 and 7 years is shaded on the sketch given at the end of this answer.
Item b:
The probability is the <u>p-value of Z when X = 7 subtracted by the p-value of Z when X = 2.8</u>, thus:
X = 7:



has a p-value of 0.9871.
X = 2.8:



has a p-value of 0.1587.
0.9871 - 0.1587 = 0.8284, thus:
