In a hypothetical study looking at the scores of 100 people in an entrance exam, it was determined that the average score was 95

blagie [28]

Answer: 0.0228

Step-by-step explanation:

Given : In a hypothetical study looking at the scores of 100 people in an entrance exam, it was determined that the average score was 95 with a standard deviation of 10.

i.e. $\mu=95\ \ \&\ \sigma=10$

Let x denotes the scores.

We assume that the scores are normally distributed.

Then, the proportion of individuals in this population have a score greater than 115 will be :-

$P(x>115)=1-P(x\leq115)\\\\=1-P(\dfrac{x-\mu}{\sigma}$

Hence , the proportion of individuals in this population have a score greater than 115 = 0.0228
