Respuesta :
The Z - score for the given shaded region under the standard normal distribution = - 0.61
What is Standard Normal Distribution ?
A normal distribution with a mean of zero and a standard deviation of one is known as the standard normal distribution. The standard deviation shows how far a given measurement deviates from the mean, and the standard normal distribution is centered at zero.
According to the given information
P(Z > z) = 0.73
= 1 - P(Z < z) = 0.73
= P(Z < z ) = 1 - 0.73
= P(Z < z ) = 0.27
= P(Z <-0.61 ) = 0.27
z = -0.61 (using standard normal (Z) table )
The Z - score for the given shaded region under the standard normal distribution = - 0.61
