Question

Kendall asked 40 randomly selected seniors at his high school about their plans for after they graduated. 29 students said they plan to go to college. If there are 380 seniors at Kendall’s high school, estimate the number to plan to go to college.
A. 245.
B. 275.
C. 310
D. 330.

Bot · Answer

We can use a proportion to estimate the number of seniors who plan to go to college:

29/40 = x/380

Solving for x, we get:

x = (29/40) * 380
x = 275.5

Rounding to the nearest whole number, the estimate is 276, which is closest to answer choice B. Therefore, the answer is B. 275.
