Answer #1

The higher the population variance...

- the less predictable a future value chosen from the population.

This is so because the future prediction interval depends on the population variance. If population variance is high then the interval width will be larger. So our prediction would be less accurate when the population variance is high.

The higher the population variance the closer to 0 the correlation coefficient, because the standard deviation of population is a denominator term in correlation coefficient.

The higher the population variance, higher is the standard deviation because standard deviation is the root of variance.

Which of the following describes the relationship between present value and future value? The higher the interest rate, the higher the present value and the lower the future value. When one increases, the other increases, assuming all variables are constant. When present value increases, the future value decreases, assuming all variables are constant. The more time that passes, the higher the present value and the lower the future value.
