Question
Suppose x is a normally distributed random variable with u = 10 and o = 2. Find each of the following probabilities.
a. P(x > 12.5) b. P(xs8) c. P(10.46<x< 14.72) d. P(4.72<xs 12.96)
Click here to view a table of areas under the standardized normal curve.
.....
a. P(x> 12.5) = .106 (Round to three decimal places as needed.)
b. P(x<8) = .159 (Round to three decimal places as needed.)
c. P(10.46<x<14.72) = .4 (Round to three decimal places as needed.)
d. P(4.72<x<12.96) =| (Round to three decimal places as needed.)
