Find the p( -1,75 < z < - 1,04 )if the random variable Z is from a standard normal population.

Question

A)0,2919
B)0,2190
C)0,1091
D)0,0991
E)0,3019

Answer 1

To find the probability, we can use a standard normal distribution table (Z-table) or a statistical calculator.

Using a Z-table, we can find the area between -1.75 and -1.04 under the standard normal curve.

The Z-score for -1.75 is -1.75 and for -1.04 is -1.04.

Looking up these Z-scores in the Z-table, we find:

P(Z < -1.75) = 0.0401
P(Z < -1.04) = 0.1480

Therefore, P( -1.75 < Z < - 1.04 ) = P(Z < -1.04) - P(Z < -1.75) = 0.1480 - 0.0401 = 0.1079

Therefore, the closest answer is:

C) 0.1091
