The duration of time from first exposure to HIV infection to AIDS diagnosis is called the incubation period. The incubation periods of 7 HIV infected individuals is given below (in years): 12.0 10.5 9.5 6.3 13.5 12.5 7.2 a. Calculate the sample mean - show your details. b. Calculate the sample median. show details c. Calculate the sample standard deviation, show details d. If the number 6.3 above were changed to 1.5, what would happen to the sample mean, median, and standard deviation? State whether each would increase, decrease, or remain the same. e. The Individuals where recruited at the "free mobile women's hospital", who serves undeserved women, individuals where payed 1500 $ for participating. Explain why is smaple may not be representative of the general population.

Measuring the height of a Yellow Meranti is very difficult because these trees grow to heights over 300 feet. In 2016, a group of Yellow Meranti in Sabah’s Danum Valley was announced as the tallest tropical trees in the world. People familiar with these trees understand that the height of a Yellow Meranti is related to other characteristics of the tree, including the diameter of the tree at the breast height of a person (in inches) and the thickness of the bark of the tree (in inches). The file YellowMeranti contains the height, diameter at breast height of a person, and bark thickness for a sample of 40 Yellow Meranti trees.
