A normal distribution has a mean equal to 46. What is the standard deviation of this normal distribution if 2.5% of the proportion under the curve lies to the right of
x = 51.88?
(Round your answer to two decimal places.)
Homework Answers
z-value = 1.96
x = mean + z * sigma
sigma = (51.88 - 46)/1.96
sigma = 3
Hence, standard deviation, sigma = 3.00
