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.
