If Professor Wilson found that the test scores of his students had a variance of 4.4, what is the standard deviation? Type a numerical answer in the space provided. Round your answer to the nearest tenth and do not type spaces in your answer.

the std dev is √4.4 = 2.1

lol this works as a name but ty

To find the standard deviation, you need to take the square root of the variance.

So, the standard deviation is √4.4 ≈ 2.1 (rounded to the nearest tenth).

Therefore, the numerical answer for the standard deviation is 2.1.
