Question

Question 2 options:

Assume Z is a standard normal random variable with mean 0 and variance 1.

Find P(Z<1.48)? Area below 1.48?

Note: Enter X.XX AT LEAST ONE DIGIT BEFORE THE DECIMAL, TWO AFTER and round up. Thus, 27 is entered as 27.00, -3.5 is entered as -3.50, 0.3750 is entered as 0.38

Assume Z is a standard normal random variable with mean 0 and variance 1.

Find P(Z>0.67)? Area above 0.67?

Note: Enter X.XX AT LEAST ONE DIGIT BEFORE THE DECIMAL, TWO AFTER and round up. Thus, 27 is entered as 27.00, -3.5 is entered as -3.50, 0.3750 is entered as 0.38

Assume Z is a standard normal random variable with mean 0 and variance 1.

Find P(-1.28<Z<2.07)?

Area between -1.28 and 2.07?

Note: Enter X.XX AT LEAST ONE DIGIT BEFORE THE DECIMAL, TWO AFTER and round up. Thus, 27 is entered as 27.00, -3.5 is entered as -3.50, 0.3750 is entered as 0.38

Find the 20th percentile of Z?

Note: Enter X.XX AT LEAST ONE DIGIT BEFORE THE DECIMAL, TWO AFTER and round up. Thus, 27 is entered as 27.00, -3.5 is entered as -3.50, 0.3750 is entered as 0.38

Assume Z is a standard normal random variable with mean 0 and variance 1.

Find z-score for which the area to its RIGHT is 0.15?

Note: Enter X.XX AT LEAST ONE DIGIT BEFORE THE DECIMAL, TWO AFTER and round up. Thus, 27 is entered as 27.00, -3.5 is entered as -3.50, 0.3750 is entered as 0.38
