Question

The standard normal curve shown

Answer 1

Answer:

C. 0.6766

Step-by-step explanation:

The area of the shaded region  between the two z-scores ;

Z=-1.3 Z=0.75

In probability notation we have;

Pr(-1.3<Z<0.75)

From the standard normal tables, we have the following cumulative probabilities;

Pr(Z<0.75) = 0.7734

Pr(Z<-1.3) = 0.0968

Pr(-1.3<Z<0.75) = Pr(Z<0.75) - Pr(Z<-1.3)

Pr(-1.3<Z<0.75) = 0.7734 - 0.0968

Pr(-1.3<Z<0.75) = 0.6766
