QuestionCalculate the standard deviation from a variance of $0.00180$ . Round to four decimal places.

Studdy Solution

STEP 1

Assumptions1. The variance for one-year CDs is $0.00180$ . We need to calculate the standard deviation3. The standard deviation is the square root of the variance

STEP 2

The formula for standard deviation is the square root of the variance. We can write this as $Standard\, deviation = \sqrt{Variance}$

STEP 3

Now, plug in the given value for the variance to calculate the standard deviation.
$Standard\, deviation = \sqrt{0.00180}$

STEP 4

Calculate the standard deviation.
$Standard\, deviation = \sqrt{0.00180} =0.04243$ The standard deviation for one-year CDs is0.04243.
