Question

180 students were asked to randomly pick one of the numbers 1, 2, 3, 4, 5, 6, 7, 8, 9, 10. The number 7 was picked by 51 students. (a) For the sample, calculate the proportion of students who picked 7. (Round the answer to three decimal places.)

Answer 1

To calculate the proportion of students who picked 7, divide the number of students who picked 7 by the total number of students and round the answer to three decimal places.

Step-by-step explanation:

To calculate the proportion of students who picked 7:

Step 1: Divide the number of students who picked 7 (51) by the total number of students (180).

Step 2: Divide the result by 10 (the number of options available) to get the proportion.

Step 3: Round the answer to three decimal places.

Therefore, the proportion of students who picked 7 is 0.283.
