Let X and Y equal respectively the blood volumes in
Let X and Y equal, respectively, the blood volumes in milliliters for a male who is a paraplegic and participates in vigorous physical activities and for a male who is able-bodied and participates in everyday, ordinary activities. Assume that X is N(μX, σ2X) and Y is N(μY, σ2Y). Following are n = 7 observations of X:
Following are m = 10 observations of Y:
Use the observations of X and Y to
(a) Give a point estimate for μX − μY.
(b) Find a 95% confidence interval for μX − μY. Since the variances σ2X and σ2Y might not be equal, use Welch’s T
