Conducting a Bivariate Regression Analysis: With fixed data

How does the wealth of a nation predict the healthy life expectancy of its citizens? The WorldHappiness Report 2021 collected data on several possible predictors of happiness. For example, the variable national wealth was highly correlated with happiness, as shown in the graph below. Using the following summary statistics, conduct a regression analysis to determine if national wealth is a statistically significant predictor of happiness. Round your answers to two decimal places.

	Happiness	PerCapitaGDP
M	5.55	9.43
SD	1.07	1.16
n	149
r	0.79
SS regression	106.46
SS residual	64.23

a. H1 : 0

b. H0 : r= 1.0

c. H0 : = 0

d. H0: = 1.0
