3. Find the probability that a randomly selected individual has a height less than 152 centimeters.

4. Can you determine the probability that a randomly selected individual has a height greater than 180 centimeters?

Solutions

Expert Solution

µ = 160

sd = 8

a)

                               

                                = P(Z < 0)

                                = 0.5

b)

                               

                                = P(Z > 2)

                                = 1 - P(Z < 2)

                                = 1 - 0.9772

                                = 0.0228

c)

                              

                               = P(Z < -1)

                               = 0.1587

d)

                               

                                = P(Z > 2.5)

                                = 1 - P(Z < 2.5)

                                = 1 - 0.9938

                                = 0.0062
