Question

Jared used a survey to determine the political views of his 250 classmates. He randomly selected 40 students to complete the survey. The survey results showed that 10 of them do not belong to a major political party.

Based on these results, about how many of his 250 classmates do not belong to a major political party?

Answer 1

To estimate the number of classmates who do not belong to a major political party, we can use the proportion of students in the sample who do not belong to a major political party as a basis.

Out of the 40 students surveyed, 10 do not belong to a major political party, so the proportion is 10/40 = 0.25.

We can then multiply this proportion by the total number of classmates to estimate the number who do not belong to a major political party:

0.25 * 250 classmates = 62.5 classmates

So about 62 or 63 of the 250 classmates are estimated to not belong to a major political party.
