Extracted text: The Harvard Step Test was developedt in 1943 as a 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 = 15.000 The following table shows how to interpret the results of the test. Efficiency index Interpretation Poor condition Low average High average Below 55 55 to 64 65 to 79 80 to 89 90 & above Good Excellent (a) Does the physical efficiency index increase or decrease with increasing values of P? O increase O decrease Explain in practical terms what this means This answer has not been graded yet. (b) Express using functional notation the physical efficiency index of someone whose total pulse count is 194. Calculate that value. (Round your answer to the nearest whole number.) (c) What is the physical condition of someone whose total pulse count is 194? O poor condition O low average O high average O good O excellent (d) Which of the following pulse counts will result in an excellent rating? O 197 O 129 O 191 O 181
