							Dear Student

For the given data: 2, 4, 5, 6, 8, 17, the variance is 23.33.

To find the variance for the data: 4, 8, 10, 12, 16, 34

If you notice the data which you have to find the variance, it is the multiple of the given data.

So, multiply the variance of the given data by 2,

It means that, 23.33 x 2 = 46.66

Hence, the variance of the data: 4, 8, 10, 12, 16, 34 is 46.66
