A researcher computes the definitional formula for SS, and finds that Σ(x − M) = 44. If this is a sample of 12 scores, then what

olga_2 [115]

Answer:

Option B.

Step-by-step explanation:

Given information:

Σ(x − M) = 44

where, M is mean.

Sample size = 12

The computational formula for sample variance is

$s^2=\dfrac{\sum (x-M)^2}{N-1}$

where, M is sample mean and N is sample size.

Substitute Σ(x − M) = 44 and N=12 in the above formula.

$s^2=\dfrac{44}{12-1}$

$s^2=\dfrac{44}{11}$

$s^2=4.0$

The sample variance is 4.0.

Therefore, the correct option is B.

Cameron has 2 video game holder stands each can hold 2 rows of 20 games write and evaluate a numerical expression to find the to

Aleksandr [31]

Answer:

so this would be the equation

2(2*10)=v

So the number on the outside is the number of stands, the second 2 is for the two rows, and the 10 is the games. I did this because its two rows and combined they make 20 games. It took me a little to figure that out.

This shows the number of games total in both holders.
