As part of an overall evaluation of training methods, an experiment was conducted to determine the average exercise capacity of healthy male army inductees. To do this, each male in a random sample of 35 healthy army inductees exercised on a bicycle ergometer (a device for measuring work done by the muscles) under a fixed workload until he tired. Blood pressure, pulse rates, and other indicators were carefully monitored to ensure that no one’s health was in danger. The exercise capacities (mean time, in minutes) for the 35 inductees are listed in the data 1. Use these data to construct a 95% confidence interval form, the average exercise capacity for healthy male inductees. Interpret your findings. Using the data, to determine the number of sample observations that would be required to estimate m to within 1 minute, using a 95% confidence interval.
