Question 1050442: The compressive strength of cement can be modeled by a normal distribution with
a mean of 6000 kilograms per square centimeter and a standard deviation of 100
kilograms per centimeter.
a. What is the probability that a sample’s strength is less than 6252 kg/cm2 ?
b. What is the probability that a sample’s strength is between 5800 and 5890 kg/cm2 ?
Answer by ewatrrr(24785)   (Show Source):
You can put this solution on YOUR website! a mean of 6000 kilograms per square centimeter and a standard deviation of 100
a) P = normalcdf(-9999, 6252, 6000, 100)
b) P = normalcdf(5800, 5890, 6000, 100)
In general:
TI syntax is normalcdf(smaller, larger, µ, σ).
