Alla [95]

Answer:

10.63

Step-by-step explanation:

Data provided in the question

Data = 30 subjects

The Variance of scores = 113.00

The calculation of standard deviation is shown below:-

As we know that

Variance = Standard deviation^2

Therefore,

Standard deviation = $\sqrt{variance}$

= $\sqrt{113}$

= 10.63

Therefore for computing the standard deviation we simply applied the above formula.

Slope Formula: $\displaystyle m = \frac{y_2 - y_1}{x_2 - x_1}$

Step-by-step explanation:

Step 1: Define

Identify points.

Point (8, 1)

Point (11, 10)

Step 2: Find slope m

Simply plug in the 2 coordinates into the slope formula to find slope m.

Substitute in points [Slope Formula]: $\displaystyle m = \frac{10 - 1}{11 - 8}$
[Order of Operations] Evaluate: $\displaystyle m = \frac{9}{3}$
Simplify: $\displaystyle m = 3$
