djverab [1.8K]

Answer:

B. −0.72

Explanation:

The correlation coefficient is a measure of the linear association between two variables.

It is a dimensionless value bettween - 1 and +1. Hence, it does not depend on the units that are used to measure the data.

You can see the formula to calculate the correlation coefficient in the attached picture.

There you see that the numerator containts the sum of the differences of the values of the x-variable with its the mean, multiplied by the sum of the differences of the values of the y variable with its mean, while the denominator contains the square root of the product of the squares of the same differences, thus the units are canceled.

In conclusion, If the teacher changes the units of each variable from hours to minutes, the value of the correlation coefficient between minutes studying and minutes spent on the Internet will not change; it will continue being −0.72.

How did nations ensure that they exported more than they imported

Zielflug [23.3K]

Explanation: If a country exports a greater value than it imports, it has a trade surplus or positive trade balance, and conversely, if a country imports a greater value than it exports, it has a trade deficit or negative trade balance.
