Use the following scenario for the next 4 questions: The HogEye Marathon is run in the spring of each year in Northwest Arkansas. In 2006 it is scheduled for March 26. The weather is highly variable this time of year, ranging from about 49 degrees to about 80 degrees. A researcher was curious if the temperature had any impact on the winning running times so she collected the results for the last 21 years and entered them into a spreadsheet as illustrated below.

Winningtimes	Temperature
132.2	75
131.7	80
129.683	50
128.217	54

15. Which of the following would be the hypothesis for this problem?

a. H0: B _temp = 0 H1: B _temp

b. H0: B _temp = 0 H1: B _temp > 0

c. H0: B _temp = 0 H1: B _temp 0

d. None of the above

The researcher ran a regression analysis and obtained the following output:
