Question 1206152
i think they're talking f test for equal variance.
i used the f test calculator at <a href = "https://www.statskingdom.com/220VarF2.html" target = "_blank">https://www.statskingdom.com/220VarF2.html</a>
results of the f-test are shown below.

you are looking for difference in variance, but the input requires standard deviation, so you need to enter the square root of the variance.
square root of 6 = 2.449489743.
square root of 10 = 3.16227766.


this is what the inputs look like.

here's a reference on the f-test for equal variance.
