Bivariate Data problem. Image attached. A. 5.967 B. 6.671 C. 9.352 D. 9.338

Fed [463]

Answer:

Step-by-step explanation:

$s_x$ is the standard deviation of x.

The standard deviation is gotten by:

1. find the average of x-values (add up all the values and divide by number of numbers, which is 5)

2. subtract the average, x bar, from each of the values, square it, and add up the difference

3. Divide that final answer by n, which is 5

4. Take the square root of the answer

Now, let's find the average (x bar):

x bar = $\frac{2+6+9+14+19}{5}=10$

Doing steps 2 & 3 together:

$\frac{(2-10)^2+(6-10)^2+(9-10)^2+(14-10)^2+(19-10)^2}{5}\\=35.6$

Doing step 4:

$\sqrt{35.6} =5.967$

Correct answer is A
