Question

In a survey, 100 students

Answer 1

To be able to determine the expected number of students who would choose spring as their favorite season, let's determine the possible ratio based on the given table.

`\frac{\text{ Number of students choosing spring}}{\text{ Total number of students in the survey}}\text{ = }\frac{\text{ }24}{24\text{ + 55 + }12\text{ + 9}}`
`\text{ }(24)/(100)\text{ = 0.24}`

Let's now determine the expected number based on the ratio of the sample in the survey,

Out of 1,300 students,

`\text{ 1,300 x 0.24 = }312`

Therefore, the answer is 312.
