For the purpose of determining the value of its end-of-year inventory, a clothing store creates a list at the end of the year of every item currently in stock along with each item's wholesale price. Which of the following is the best description of the end-of-the-year activity? a. An experiment, because the items are treatments and wholesale prices are responses.
b. An experiment, because the store does not know the total wholesale price of all the items.
c. A sample survey, because the store wants to estimate the value of all items for the entire year.
d. A sample survey, because the items currently in the store at the end of the year are a random sample of all items in the store for the entire year.
e. A census, because the wholesale prices of all items are listed.
