Question 926197: Use the standard normal distribution table in the book to solve the following problems. Z here represents a random variable that is standard normally distributed. Round all answers to four places after the decimal point.
Find the probability Pr(Z < -1.05) .
Find the probability Pr(Z > -1.05) .
Find the probability Pr(-3.10 < Z < 2.15) .
Find the number b such that Pr(Z > b)= .9821 .

Find the probability Pr(Z < -1.05) = normalcdf(-100,-1.05) = 0.1469
Find the probability Pr(Z > -1.05) = normalcdf(-1.05,100) = 0.8531
Find the probability Pr(-3.10 < Z < 2.15) = normalcdf(-3.1,2.15) = 0.9833
Find the number b such that Pr(Z > b)= .9821 .
Find the z-value with a left tail of 1-0.9821 = 0.0179
b = invNorm(0.0179) = -2.0992
