Question

Kendall asked 40 randomly-selected seniors at his high school about their plans for after they graduated. Twenty-nine students said they planned to go to college. If there are 380 seniors at Kendall's high school, estimate the number who plan to go to college.

Answer 1

can someone please help me?

Answer 2

Ok, to start, let's get a percentage. This is done by dividing the number of students that plan to go to college by the total number that they interviewed. So, what does that come out as as a decimal?

Answer 3

a) 245
b) 275
c) 310
d) 330

Answer 4

Those are you possible options, but please answer my question.

Answer 5

0.67?

Answer 6

Try again. Did you do 29/40?

Answer 7

oh 29/40 is 0.725

Answer 8

Correct, now, given that .725 is the same as 72.5%, we now know that about 72.5% of people sampled are going to college. Thus, probability tells us that if we multiply that percent by the total number of students at the school, we'll get a number close to the real number, had everybody been interviewed. So, please do that.

Answer 9

27550?

Answer 10

No, remember that when multiplying something by a given percentage, you have to make it a decimal first.

Answer 11

ok so .725*380?

Answer 12

is 725.5

Answer 13

so the answer is 725? right?
