Answer:

The answer to your question is below

Step-by-step explanation:

Process

1.- Transform the inequality to a line

2x - y < 4

2x - y = 4

2.- Find the x and y-intercepts

If x = 0, 2(0) - y = 4

0 - y = 4

y = -4 (0, -4)

If y = 0 2x - 0 = 4

2x = 4

x = 2 (2, 0)

3.- Do not consider graphs 1 and 2 because do not go through (0, -4).

4.- The answer is graph three because of the inequality "<", we look for the shaded region below the line.

For a repeated-measures study comparing two treatments with a sample of n = 9 participants, the difference scores have a mean of

Korolek [52]

Answer: Estimated standard error for the sample mean difference would be 1.

Step-by-step explanation:

Since we have given that

Mean of MD = 4.90

So, Sum of difference would be

$4.9\times 9=44.1$

S = 288

n = 9

We need to find the standard error for the sample mean differences.

Estimated standard error for the sampled mean difference would be

$\dfrac{\sqrt{Sum(D^2)-(\dfrac{sum(d)^2}{n})}}{n(n-1)}}\\\\=\dfrac{\sqrt{288-\dfrac{44.1^2}{9}}}{9(9-1)}\\\\=0.99\\\\\approx 1$

Hence, estimated standard error for the sample mean difference would be 1.
