Do wearing custom-made shoes, made specifically for the runner, help a runner run faster? To answer this question, twelve competitive runners were randomly selected and their maximum velocity (in mph) was recorded while wearing the custom-made shoes and then again while not wearing the custom-made shoe. (A time for rest was granted and it was randomly determined if they ran with the custom-made shoes first or second. The runners ran 100 yards.) Custom shoes 23.2 20 17.6 22.9 21.5 23 20.8 18.9 | 24 18.8 19.2 19.3 Regular shoes 14.8 16.1 15.4 18 20.4 18.2 19.3 16.3 19 19.6 18.4 | 18.5 a. At the 5% significance level, what conclusion can be reached? b. Are the samples independent or dependent? c. Ifindependent, would using dependent samples have been better? Why or Why not? If depen- dent, explain why dependent samples were used.

The valence of a song is measured from 0 to 10 and detects the musical positiveness conveyed in the song. Tracks with high valence sound more positive (e.g. happy, ch with low valence sound more negative (e.g. sad, depressed, angry).

The Margaria-Kalamen test is used by physical educators as a measure of leg strength. An individual runs up a staircase, and the elapsed time from the third to the ninth step is recorded. The power score is calculated using a formula involving the individual's weight, the height of the stairs, and the running time. The following tablet shows the power scores required of men for an excellent rating for selected ages. Age 18 25 35 45 55 Power score for excellent rating 224 210 168 125 98 (a) What is the average rate of change per year in excellence level from 18 years to 25 years old? -2 points per year (b) What power score would merit an excellent rating for a 20-year-old man?
