Answer:
the probability when the IQ is lower than 136 is 0.9641
Step-by-step explanation:
Given that
The mean is 100
The standard deviation is 20
We need to find out the probability when the IQ is lower than 136
So,
z value equivalent to 136 = (136 - 100) ÷ 20 = 1.8
Now
p (z < 1.8) = 0.9641
hence, the probability when the IQ is lower than 136 is 0.9641
With this question, you are just going to add up the three numbers
1,300 + 1,400 + 1,500
This equals 2,200
