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, 72.058294<μ(Pulse) < 75.416208 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. OA. The interval 72.1 to 75.4 beats per minute contains the true mean heart rate 95% of the time. OB. We are 95% confident the interval 72.1 to 75.4 beats per minute contains the true mean heart rate. OC. 95% of all pulse rates will have a mean rate between 72.1 to 75.4 beats per minute. OD. 95% of the pulse rates will be between 72.1 to 75.4 beats per minute. b) What's the margin of error for this interval? (Round to one decimal place.) c) If the researcher had calculated a 90% confidence interval, would the margin of error be larger or smaller? A The marnin of error would have remained the same
