Answer 1

Given:

$μ=0$

As we have to find the probability of reading falling between 0.25 and 1.50, we have to calculate the area under the normal curve between z=0.25 and z=1.50. Thus 'A' is the correct plot. To find the required probability:

(see how to get these values from the table in the images attached below)

Thus the required answer is 0.3345.

P(z=0.25) = 0.5987 (see in image below)

P(z=1.50) = 0.9332 (see in image below)
