Answer: tbh Idk, but my bed answer would be C.

Step-by-step explanation:

On the online calculator, Desmos, I used these steps -

1. At The Top Left, there is a plus icon and in that icon I went down to table

2. Once the table was up, I entered the data and went to the next line under

3. At The Bottom Left, there is a keyboard icon and in that icon, over to the right, there is a functions button

4. Click the button and go over to STATS

5. Under stats, on the left and three down, you see "stdev", or standard deviation

6. Click that and in the parenthesis, if you didn't change the tables "x_1" and "y_1", use "x_1" (shift - underscore)

This gives you the stdev of DATA SET A

To get stdev of DATA SET B -

7. After getting stdev of DATA SET A, 6.633, go to the next line under and repeat steps 5&6, but replace "x_1" with "y_1".

(DATA SET B stdev is 1.290)
