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, 65.961748<μ(Pulse)<69.918067 1.) Explain carefully what the software output means. A. The interval 66.0 to 69.9 beats per minute contains the true mean heart rate 95% of the time. B.We are 95% confident the interval 66.0 to 69.

Question
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, 65.961748<μ(Pulse)<69.918067
1.) Explain carefully what the software output means.
A. The interval 66.0 to 69.9 beats per minute contains the true mean heart rate 95% of the time.
B.We are 95% confident the interval 66.0 to 69.9 beats per minute contains the true mean heart rate.
C. 95% of the pulse rates will be between 66.0 to 69.9 beats per minute.
D. 95% of all pulse rates will have a mean rate between 66.0 to 69.9 beats per minute.
2) What's the margin of error for this interval?
3) If the researcher had calculated a 99% confidence interval, would the margin of error be larger, smaller, or the same?
