1 answer:
Alex_Xolod [135]3 years ago
5 0

Answer:

D. 22%

Step-by-step explanation:

89 of the 374 cars in the table are red. Without knowing more about the sampling process used to obtain the table data, the best we can do is assume that proportion holds for the whole country.

_____

Using these numbers gives higher weight to larger samples, which does not seem unreasonable—unless the larger sample favors red cars for some reason.
