b)How are r and bY related?

c)Of what value is it to know the standard error of estimate for a set of paired X and Y scores?

d)The addition rule gives the probability of occurrence of any one of several events, whereas the multiplication rule gives the probability of the joint or successive occurrence of several events. Is this statement correct? Explain, using examples to illustrate your explanation.

Solution

b)How are r and bY related?

linear related

c)Of what value is it to know the standard error of estimate for a set of paired X and Y scores?

SD = sigma / srqt(n)
