Find the probability of selecting a z score less than 1.81

The probability of selecting a z score less than 1.81 is 0.9649 or 96.49%

Step-by-step explanation:

Z score represents the number of standard deviations that the score is either above or below the mean.

If the Z score is 0, the score is identical to the mean score. Hence its probability becomes 50% as equal parts of score are below the mean and above the mean.

As here the z score is given to be 1.81, from the Z score table we get,

r(0,90)(x,y) . t(-5,0)

last option

step-by-step explanation:

∆def to ∆d"e"f"

- rotate 90 counterclockwise degrees

- then translated 5 to the left (x --> x - 5)

answer is the last option
