Find the sample standard deviation for the given data. Round your final answer to one more decimal place than that used for the observations. 2, 6, 15, 9, 11, 22, 1, 4, 8,19

A. 6.3
B. 7.1
C. 6.8
D. 2.1

So, the sample standard deviation is 7.1.

Step-by-step explanation:

From Exercise we have the next numbers:  2, 6, 15, 9, 11, 22, 1, 4, 8,19.

So, N=10, because we have 10 numbers.

We use the formula for standard deviation:

So,  μ  is the mean of all our values.

We get:

Now, we calculate the sum

Therefore, we get

So, the sample standard deviation is 7.1.

the answer is 11.2 (i know i’m late)

then
