Answer:

The answer is 525

Explanation:

35 out of 200 people is 7/40 of the people. to find 7/40 of 3,000 you need to divide 3000 by 40 and multiply that with 7. This should give you the answer 525

Solution 1

Total people whose first concert:

(probability of first concert from sample) * total people

  • (35/200) * 3000
  • 525 people's first concert

Solution 2

a) A random sample because here the interview is with a large group of boys.

b) A fair question as people who don't like football as well can sometimes try out football. So asking them for thier favourite sports is fair.
