Leya [2.2K]

Answer:

A) a small variance for the difference scores and a small standard error

Step-by-step explanation:

Since the difference scores are obtained by subtracting one variable form another, if the difference scores are consistent between treatments, then the variance will be small. The higher the variance, the higher the standard error. So if the variance is small, then the standard error will also be small.

What is an equation of a line that passes through the point
AlekseyPX

Answer:  <u>y = -(1/2)x + 3</u>

<u></u>

Step-by-step explanation:

<u>y = 2x - 1</u>

This is in the format of y=mx + b, where m is the slope and b is the y-intercept (the value of y when x=0).

Perpendicular lines have a slope that is the negative inverse of the reference line.  The slope of this reference line is 2, so the slope of a perpendicular kline will be -(1/2).

This yields the equation y = -(1/2)x + b

To find the value of b, we can use the given point, (0,3) and use these values of x and y to solve for b:

y = -(1/2)x + b

3 = -(1/2)(0) + b

b = 3

The equation of a line perpendicular to y = 2x - 1 and goes through point (0,3) is:

y = -(1/2)x + 3

11d + 17d – -3d + -12d – 17d = -12
Vikki [24]
11d + 17d - (-3d) + (-12d) - 17d = -12

11d + 17d + 3d -12d - 17d = -12

2d = -12      |divide both sides by 2

d = -6
