In a set of normally distributed test scores that have a mean of 100 and standard deviation of 15, it would be correct to conclude that approximately 68 percent of the scores would fall between and

It would be correct to conclude that approximately 68 percent of the scores would fall between 85 and 115.          

Step-by-step explanation:

We are given the following in the question:

Mean, μ = 100

Standard Deviation, σ = 15

We are given that the distribution is a bell shaped distribution that is a normal distribution.

Empirical rule

Thus, approximately 68% of data will lie within one standard deviation of mean.

Thus, it would be correct to conclude that approximately 68 percent of the scores would fall between 85 and 115.

x = -2

y = 848

step-by-step explanation:

plug in the numbers

the answer is d

step-by-step explanation:

y+3=-4(x-2)

y+3=-4x+8
