Question

Select Yes or No to state whether each data set is likely to be normally distributed.

Answer 1

Just took the test and this screenshot is from the review of it.

Answer 2

we know that

Normal distribution:

The normal distribution is a very common continuous probability distribution

A probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean

now, we will check each options

option-A:

we know that number of coupons will always be counted

so, it is discrete in nature

so, this is not normal distribution

option-B:

we know that

the weights of the pumpkins that are delivered to a supermarket can be any values

so, this will be continuous in nature

so, this is normal distribution

option-C:

the number of raisins in each 8-oz box of raisins at a supermarket

number will always be counted

so, this is discrete in nature

so, this is not normal distribution

option-D:

the amount of time customers spend waiting in the checkout line at a supermarket

time can be decimal or number

so, this is continuous in nature

so, this is normal distribution
