Answer:

The Variance will be 6.3.

Step-by-step explanation:

Note: You probably unintentionally missed to mention the standard deviation in your question. After a little research, it seem that standard deviation is 2.5 in your question that you should have mentioned in your question. Anyways, I am assuming the standard deviation as 2.5, and based on this, answering your question. It anyways will clear your concept, hopefully.

The complete version of Question:

Ms. Johnson uses a statistics program to analyze all the data collected by her students during a lab experiment about the acceleration due to gravity. The program reports a mean of 31.5 and a standard deviation of 2.5.

What is the variance of the data? Round to the nearest tenth.

1.6 2.5 5.6 6.3

Solution:

As the standard deviation = σ = 2.5

As the know that Standard deviation (σ) is equal to the square root of the variance.

σ = $\sqrt{v}$
