Judge and Cable (2010) report the results of a study demonstrating a negative relationship between weight and income for a group of women professionals. Following are data similar to those obtained in the study. Income figures are rounded to the nearest $1,000.

BMI (X)	Income (Y)
22	125
26	78
37	49
31	63
40	35
27	84
42	38
33	51
24	93
38	44
SS_X	SS_Y
452	7430

Conduct a Pearson’s r hypothesis test to determine if there is a statistically significant correlation between weight and income. Use a two-tailed test with α = .05.

A researcher wants to determine if there is a linear relationship between height and weight. The following table represents the data collected. Display the data in a scatter plot on your calculator, draw a quick sketch below. Then find the linear regression and put the line of best fit on the sketch. Then state the value for the correlation coefficient and determine if this is a positive correlation or no correlation using the table in the back of the book....

The relationship between income and saving is ( direct, inverse; positive, negative ). That means, as income increases, the amount of saving ( increases, decreases, stays the same ). What is the slope of the line? Slope = ________ = Vertical changes ÷ Horizontal changes The slope shows the amount of changes in savings due to the changes in income. That is, for every $1 increase in income, the amount of increase in saving will be $_____. The vertical intercept?...

1. Direct relationship: A relationship between two variables, where a change in one variable results in the same change in the other variable. For example, if one variable is increased, then the other variable will also increase. Indirect relationship: A relationship between two variables, where a change in one variable results in the opposite change in the other variable. For example, if one variable is increased, then the other variable will decrease. a. Considering the terms described above, do the...
