Answer:

D

Step-by-step explanation:

Here, we want to get the proportion that lies outside the given shown z-scores

Mathematically, that will be:

1 - proportion lying between the two z-scores

The probability lying between the two z-scores can be calculated using the normal distribution table

That will be;

P(-1.25 < x < 0.80)

From the table, this is;

0.68249

So the proportion lying outside will be;

1-0.68249 = 0.31751

This is approximately 0.3175
