Question 2 5 points A running coach wanted to see whether runners run at a different speed after eating spaghetti the night before a race. For a 5-km race, two samples were chosen: 9 runners who had a regular dinner the night before and 6 runners who had a spaghetti dinner the night before. Their results (in seconds) are in the table below. At a = 0.04, assuming unequal population variances, and using the Welch-Satterthwaite (i.e., exact) equation to calculate the degrees of freedom, do the data support the alternative hypothesis that runners do indeed run at a different speed after eating spaghetti?
