State whether one would expect the data set described below to be normally distributed. Explain why or why not.

The exact weights of a random sample of wrenches manufactured by a hardware company

A. One would expect this data set to be normally distributed.

All manufactured

products,

like wrenches are designed to have exactly the same weights sothe

distribution

willonly

include

one value.

B. One would not expect this data set to be normally distributed.

Data like the weights

of wrenches tend to have a uniform distribution because each value is equally likely.

C. One would not expect this data set to be normally distributed.

All manufactured products,

like wrenches are designed to have exactly the same weights, sothe

distribution

will only

include

one value.

D. One would expect this data set to be normally distributed.

It is common

for a

manufactured

product such as wrenches, to have a distribution

that is normal. The

weights typically vary

above and below the mean weight by about

the same amounts, so

the distribution has one

peak and is symmetric.
