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, 65.946814 < mu​(Pulse) < 70.928411 ​

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?

Provide an appropriate response. A researcher was interested in comparing the resting pulse rates of people who exercise regularly and people who do not exercise regularly. Independent simple random samples were obtained of 16 people aged who do not exercise regularly and 12 people aged who do exercise regularly. The resting pulse rate (in beats per minute) of each person was recorded. The summary statistics were as follows. Do Not Exercise: x1= 73.0, s1=10.3, n1=16 Do Exercise: x2=69.9, s2=8.2, n2=...
