Josephine owns a diner that is open every day for breakfast, lunch, and dinner. She offers a regular menu and a menu with daily specials. She wanted to estimate the percentage of her customers who order specials. She selected a random sample of 50 customers who had lunch at her diner during a three-month period. She determined that 28% of these customers ordered from the menu with specials.
Which statement about Josephine's sample is true?
A
The sample is the percentage of customers who order daily specials.
B
The sample might not be representative of the population because it only included lunch customers.
C
The sample shows that exactly 28% of Josephine's customers ordered daily specials.
D
No generalizations can be made from this sample, because the sample size of 50 is too small.
