According to the college board, sat critical reading scores from the 2015 school year for high school students in the united states were normally distributed with a mean of 495 and a standard deviation of 116. use a standard normal table such as this one to determine the probability that a randomly chosen high school student who took the sat in 2015 will have a critical reading sat score between 400 and 600 points. give your answer as a percentage rounded to one decimal place

61.1% of  high school student who took the SAT in 2015 will have a critical reading SAT score between 400 and 600 points.

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 495

Standard Deviation, σ = 116

We are given that the distribution of scores from the 2015 school year for high school students in the United States is a bell shaped distribution that is a normal distribution.

Formula:

P(SAT score between 400 and 600 points)

Thus, 61.1% of  high school student who took the SAT in 2015 will have a critical reading SAT score between 400 and 600 points.
