Question 1055250: The population of lengths of aluminum coated steel sheets is normally distributed with a mean of 30.05 inches and a standard deviation of 0.2 inches. What is the probability that the sheet selected at random from the population is between 30.25 and 30.65 inches long?
Answer by ewatrrr(24785)   (Show Source):
You can put this solution on YOUR website! The TI syntax is normalcdf(smaller, larger, µ, σ).
P(30.25 ≤ x ≤ 30.65)= normalcdf(30.25,30.65,30.05,.2)
