A. Yes, it asks all the girls present in the shop
B. Yes, the sample is restricted within the shop
C. No, the sample is only about ice cream flavors
D. No, it asks only the girls in the shop

Respuesta :

Answer:

D

Step-by-step explanation:

Answer:  D. No, it asks only the girls in the shop

Erica's survey leaves out the boys which means the boys are completely under-represented while the girls are over-represented. The population consists of boys and girls. This means the sample needs to have the same proportional mix of those genders (ie around 50% for each) if you want the sample to be representative of the population.
