Harvard Step Test The Harvard Step Test was developed4 in 1943 as physical fitness test, and modifications of it remain in use today. The candidate steps up and down on a bench 20 inches high 30 times per minute for 5 minutes. The pulse is counted three separate times for 30 seconds each: at 1 minute, 2 minutes, and 3 minutes after the exercise is completed. If P is the sum of the three pulse counts, then the physical efficiency index E is calculated using E=15,000P. The following table shows how to interpret the results of the test. Efficiency Index Interpretation Below 55 Poor condition 55 to 64 Low average 65 to 79 High average 80 to 89 Good 90 & above Excellent a. Does the physical efficiency index increase or decrease with increasing values of P? Explain in practical terms what this means. b. Express using functional notation the physical efficiency index of someone whose total pulse count is 200, and then calculate that value. c. What is the physical condition of someone whose total pulse cont is 200? d. What pulse counts will result in an excellent rating?

Spache Readability Formula The Spache Readability Formula3 is designed to categorize reading materials for grades 1 through 3. For a passage of text, the variables are S, the number of sentences: W, the number of words; and U, the number of unfamiliar words words not on a specific list. The formula as revised for the grade level is Grade level =0.121WS+0.082U+0.659. The calculated grade level is rounded down to its whole number part. For example, 2.6 is round down to 2. In this exercise, we consider passages having 200 words and using 10 unfamiliar words. a. As the number of sentences increases, does grade level increase or decrease? b. What is the maximum possible number of sentence? Can there be more sentences than words? c. What is the minimum number of sentences that would put this passage at the second-grade level?

pH of Saliva The pH of saliva is normally in the range of 6.4 to 7.0. However, when a person is ill, the persons saliva becomes more acidic. a When Marco is sick, he tests the pH of his saliva and finds that it is 5.5. What is the hydrogen ion concentration of his saliva? b Will the hydrogen ion concentration in Marcos saliva increase or decrease as he gets better? c After Marco recovers, he tests the pH of his saliva, and it is 6.5. Was the saliva more acidic or less acidic when he was sick?
