The number of nails of a given length is normally distributed with a mean length of 5 in. and a standard deviation of 0.03 in. in a bag containing 120 nails, how many nails are more than 5.03 in. long?
a. about 38 nails
b. about 41 nails
c. about 16 nails
d. about 19 nails

(D) About 19 nails

Step-by-step explanation:

It is given that mean length= 5 inches and the standard deviation =0.03.

In order to standardize x to z, we use the formula=.

Now, probability of nails having length more than 5.03=

=

= b(Using the normal probability table)

In a bag of 20 nails, nails having length more than 5.03 inches==

= about nails.
