Question

Find the area under the standard normal distribution curve to the right ofz = –1.27.

Answer 1

Answer: Determine the area under the standard normal curve that lies between Z=-1.27 and Z=0.58

Explanation:

Answer 2

hello

to solve this question, we need to use a standard normal table (z)

out z-value give = -1.27

this is equivalent to 0.4032

note, i approximated 1.27 to 1.3 and the z-value for -1.3 = 0.4032

to compensated tp the other side of the graph, we should add 0.5 to 0.4032

`0.4032+0.5=0.9032`

the area under z = -1.27 is equal to 0.9032 square units or 90.32%
