Ans:
A) A statistical procedure that works reasonably well even when one of its assumptions violated is said to be robust.
Since, robust statistic means statistics that yield good performance when data is drawn from a wide range of probability distributions that are largely unaffected by outliers or small departures from model assumptions in a given dataset.

/courses/1631958/q 2791378/take D Question 5 12 pts Pulse Rates of Men. A simple random sample of 40 men results in a standard deviation of 10.3 beats per minute (based on the data set provided). The normal range of pulse rates of adults is typically given as 60 to 100 beats per minute. If the range rule of thumb is applied to that normal range, the result is a standard deviation of 10 beats per minute. Use the sample results with...

A Routine Endoscopic Procedure Our mother usually had an endoscopic procedure every 2 years. We thought that she had too many visits with her gastroenterologist. She saw the gastroenterologist about every 30 or 60 days.

Our mother had an endoscopy of her upper gastrointestinal tract in September 2006....
