Find the indicated area under the standard normal curve.
To the left of z= -1.09 and to the right of z= 1.09
A) The total area to the left of z= −1.09 and to the right of z= 1.09 under the standard normal curve is:_______? (Round to four deciamal places as needed).
We have to find the probability
using the property
so, we can write it as
again, using property
we can write
Using z distribution table, for z value 1.09, p value is 0.8621
setting the value, we get
So, required area or probability is 0.7242 (rounded to 4 decimals)
