Question

Suppose x is a normally distributed random variables with mu = 14 and sigma = 2. Find each of the following probabilities P(x greaterthanorequalto 15.5) P(x lessthanorequalto 10.5) P(14.78 lessthanorequalto x lessthanorequalto 18.9) P(8.84 lessthanorequalto x lessthanorequalto 17.02) Click here to view a table of areas, under the standardized nonnal curve. P(x greaterthanorequalto 15.5) = 0.227 (Round to three decimal places as needed.) P(x lessthanorequalto 10.5) = (Round to three decimal places as needed.)

Explanation / Answer

P( z < 10.5 - 14 / 2 )

P( z <-1.75 ) = 0.040
