Suppose you take a survey of all the schools in your state. what would you expect the relationship between the number of students and the number of teachers in each school to be?
a)positive correlation
b)not enough information
c)no correlation
d)negative correlation

A) Positive correlation

Step-by-step explanation:

Whenever we take survey of all the schools in our state to study the relationship between the number of students and the number of teachers in each school, we find that for more students more teachers are required

If there is a less number of students, then number of teachers also would be less.

Here number of students in the school is the independent variable x and no of teachers the dependent variable y.

Since increase of x causes automatic increase of y in normal course, we find that there has to be a positive correlation between x and y

Hence option A is right

A) Positive correlation
