Answer:
Between (-0.675, 0.675)
Step-by-step explanation:
We know that a standard normal distribution curve is bell shaped unimodal , symmetrical about mean.
for thsi standard normal variate with notation z, we get mean =0 and std deviation = 1
For the middle shaded region, we find z such that the area between -z and z is 0.50 exactly half.
From standard normal distribution table, we get that z= ±0.675
Hence between z=-0.675 and z = 0.675 we get the middle region with area equal to exactly 1/2.
Between (-0.675, 0.675)
