Ответ:
D. 0.7611
Step-by-step explanation:
The area is:
P(z<1.60) − P(z<-0.90)
Looking up the values in a z-score table:
0.9452 − 0.1841
0.7611
Ответ:
D. 0.7611
Step-by-step explanation:
We have been given a graph of a normal standard distribution curve. We are asked to find the area of the shaded region under the given standard distribution curve.
The area of the shaded region under the standard distribution curve would be area of a z-score of 1.60 minus area of a z-score of
that is ![P(-0.90](/tpl/images/0089/5427/01637.png)
Using normal distribution table, we will get:
Therefore, the shaded area under the curve is 0.7611 and option D is the correct choice.
