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( Mu x sigma 2/y Following are n = 7 observations of X : 1612, 1352, 1456, 1222, 1560, 1456, 1924. Following are m =10 observations of Y : 1082, 1300, 1092, 1040, 910, 1248, 1092, 1040, 1092, 1288. Use the observations of X and Y to (a) Give a point estimate for Mu y sigma 2/x ) and Y is N (Mu x

Solution

Mean = (sum of x)/n = 10582/7=1511.71

The required point estimate = 1511.71
