Run a Hypothesis test to determine if there IS a linear correlation in the population of all husbands and wives at the 5% significance level: You may use any appropriate hypothesis test method. 

a. State Hypothesis (in symbols): 

 

b. Null: 

H0: There is no significant linear correlation in the population of all husbands and wives.

c. Alternate: 

Ha: There is a significant linear correlation in the population of all husbands and wives.

d. Test Statistic: 

e. Critical value(s): 

f. Initial conclusion: 

g. Formal Conclusion: 

h. Find the regression line (even if there isn’t a correlation in the population) 

i. Write the meaning of the slope of the regression line:
