Answer:
you divide the nominator by the denominator
Step-by-step explanation:
For example:
10/15
so 10 divided by 15= .6666...
10/15 as a decimal is .6 repeating
Answer:
The equation for regression line and predicting a husband's height for married couples in their early 20s
Equation: Y'=33.67+0.54*X'
Step-by-step explanation:
r=0.5
x'=64.5
Sx=2.5
y'=68.5
Sy=2.7
General regression line equation is:
Y'=a+b*X'
so the slope of the regression line is the linear correlation coefficient multiplied by the standard deviation for y' divided by the standard deviation for x'

The intercept with axis y is the mean of the decreased by the product of the slope and the mean of x

The equation regression line then is:
Y'=33.67+0.54*X'
You add them and then divide by how many numbers there are.
a. (3+43)/2 = 23
b. 0
c. -1
