A local athletic facility offers a four-week training course, hoping to increase athletes’ running speeds. Thirty-five volunteer athletes are timed, in seconds, running a 50-yard dash before the training program begins and then again after the program is complete. The difference in running times (before training – after training) is calculated for each athlete. What are the hypotheses the facility should use?
Answer
A
H Subscript 0 Baseline: Mu Subscript difference Baseline = 0; H Subscript alpha Baseline: Mu Subscript difference Baseline less-than 0
B
H Subscript 0 Baseline: Mu Subscript difference Baseline = 0; H Subscript alpha Baseline: Mu Subscript difference Baseline greater-than 0
C
H Subscript 0 Baseline: mu First = mu second; H alpha: mu first less-than mu second
D
H Subscript 0 Baseline: mu before = mu after; H Subscript alpha Baseline: mu before less-than mu after
