what are the answers? 1. -/2 POINTS DEVORESTAT9 7.E.507.XP. MY NOTES ASK YOUR TEACHER A triathlon consisting of swimming, cycling, and running is one of the more strenuous amateur sporting events. An article reports on a research study involving nine male triathletes. Maximum heart rate (beats/min) was recorded during performance of each of the three events. For swimming, the sample mean and sample standard deviation were 186.0 and 7.5, respectively. Assuming that the heart-rate distribution is (approximately) normal, construct a...
A journal article reports that a sample of size 5 was used as a basis for calculating a 95% CI for the true average natural frequency (Hz) of delaminated beams of a certain type. The resulting interval was (229.866, 233.602). You decide that a confidence level of 99% is more appropriate than the 95% level used. What are the limits of the 99% interval? [Hint: Use the center of the interval and its width to determine x and s.] (Round...
