Mandy has an IQ of 115. We know that the mean () IQ is 100 with a standard deviation of 15. There are 100 people in Mandy’s Alc
Alex787 [66]

Answer: 16

Step-by-step explanation:

Given : Mean : \mu=100

Standard deviation : \sigma =15

The value of z-score is given by :-

z=\dfrac{x-\mu}{\sigma}

For x= 115

z=\dfrac{115-100}{15}=1

The p-value : P(z>1)=1-P(z

Now, the number of people smarter than Many is given by :_

100\times0.1586553=15.86553\approx16

Hence, there are 16 members smarter than Mandy.
