The area under a standard normal distribution is ___ and the area to the left of a Z score of -1 is _____. Group of answer choices
.5, .841
1, .158
0, 1
1, .841
Solution :-
Total area under standard normal distribution is always 1 .
Now ,
To find area to the left of -1 , use z table. see the column of z .see -1 and then see corresponding value at .00
The value is 0.158
Therefor ,
1, 0.158 ( Option 2nd is correct. )
