There are 970 students in bayton high school. Brian takes a random sample of 100 students. He asks these 100 students which subject they like best. They can choose English or Maths or Science. Brian is going to use his results to work out an estimate of how many of the 970 students like English best. Explain how.

How to do the estimation

Step-by-step explanation:

He can use the probability of how many people chose English and multiply by 9.7 since there are 970 people / 100 people who asked = 9.7

answer: the answer is one of

step-by-step explanation:   we are given to write a proper fraction where the whole is divided into an even number of equal parts less than ten, and an odd number of those parts exist.

an even number less than 10 may be one of 2, 4, 6 or 8. so, the whole may be one of these four evens.

now, an odd number of these parts must exist, so the numerator must be an odd number, one of 1, 3, 5 or 7. it cannot be 9 because then the fraction will become improper.

thus, our fraction may be one of the following
