Question

14.1.23 A medical researcher measured the pulse rates (beats per minute) of a sample of randomly selected adults and found the following Student's t-based confidence interval: With 95.00% Confidence, 73.344056 < ?(Pulse) < 76.534785 a) Explain carefully what the software output means. b) What's the margin of error for this interval? c) If the researcher had calculated a 90% confidence interval, would the margin of error be larger or smaller? a) Explain carefully what the software output means. A. 95% of the pulse rates will be between 73.3 to 76.5 beats per minute. B. We are 95% confident the interval 73.3 to 76.5 beats per minute contains the true mean heart rate. C. 95% of all pulse rates will have a mean rate between 73.3 to 76.5 beats per minute. D. The interval 73.3 to 76.5 beats per minute contains the true mean heart rate 95% of the time. b) What's the margin of error for this interval? (Round to one decimal place.)
