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?

The TI syntax is normalcdf(smaller, larger, �, σ).
P(30.25 ≤ x ≤ 30.65)= normalcdf(30.25,30.65,30.05,.2)
