For Alma to be accepted into her favorite college, she will have to earn an entrance exam score at least 2 standard deviations above the mean. Assume entrance exam scores are normally distributed, with a mean of 800 and a standard deviation of 40. What exam score does Alma need to be accepted at her favorite college?
720
760
840
880
if the mean is 800 and the standard deviation is 40, she needs two of the standard deviation added to 800. Which makes the equation: 800 + 40 + 40 which equals 880.
