Question

suppose the correlation coefficient between the number of the college students in a city and the number of city buses is 0.89. which statement must be true?

Answer 1

As the number of college students increases, the number of buses tends to increase.

Answer 2

Explanation:

Given that the correlation coefficient between the number of college students in a city and the number of city buses is 0.89.

We find that correlation coefficient is a measure of linear association between two variables.

When the absolute value of correlation coefficient is near 1, there is strong correlation. If correlation has a positive sign, there is a posiitive association between the two variables.

Here the correlation coefficient is positive and also near 1. Thus there is a strong linear correlation between the two variables.

Or whenever there is an increase in one variable there will be an increase in other variable also.
