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
