Question
Please solve question 2, I have solved question 1 but can't quite get question 2
**Problem 1:** Suppose a mean has been computed to be 92, but later it's discovered that 10 data items were inadvertently omitted. The mean of these 10 data items is 101, and the full data set has 37 data items. What is the actual mean of the full data set? **Problem 2:** Hortense Blumpstead claims that while the average person (of those she's measured) is 66" tall, there is a lot of variation. Specifically, she says that in her data set, the standard deviation of height is 47, and that 10% of people are taller than 5'6". Is it possible to call Hortense out for making stuff up and/or mathematical errors, on the basis of the information she reports? Or, is the scenario Hortense claims actually possible? Explain. (If it's not possible, say why, and if it is possible, give an example data set.)
