The time, X minutes, taken by a company to install a satellite dish may also be assumed to be a normal variable, but with the following conditions: P(X <170) = 0.14 and P(X > 200) = 0.03 i. Determine z, for P(X <170)= 0.14 and z, P(X > 200)= 0.03 i. Write two equations based on information in i. ii. Find the values for the mean and standard deviation of X by solving the two equations simultaneously.

Question
a) The time, X minutes, taken by a company to install a satellite dish may also be assumed to be a normal variable, but with the following conditions: Р(x <170)- 0.14 P(X < and P(x > 200) = 0.03 Determine z, for P(X <170)= 0.14 and z, P(X > 200) = 0.03 i. i. Write two equations based on information in i. iI. Find the values for the mean and standard deviation of X by solving the two equations simultaneously.
