Use the following sample to estimate the population proportion of red automobiles in the united states. a. 19% b. 20% c. 21% d. 22%

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.

... 89/374 ≈ 22% . . . . matches selection D

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

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3

your answer is  

a.
