The ratio of students who studied last weekend to the total number of college students in the survey is 40/42. We can use this ratio to estimate the number of students who studied last weekend out of the total college population.
Let x be the number of students who studied last weekend out of the total college population.
40/42 = x/8262
Cross-multiplying, we get:
42x = 40 * 8262
42x = 330,480
x = 330,480 / 42
x ≈ 7,872
The best estimate of the number of students who studied last weekend is 7,872.
Therefore, the best option is B. 7,869.
