Question
Suppose you have the following information on a population's parameters : = 20 interquartile range=20 median = 20 range = 40 a, DO NOT ASSUME
Suppose you have the following information on apopulation's parameters:
= 20
interquartile range=20
median = 20
range = 40
a,DO NOT ASSUME ANYTHING ABOUT THE DISTRIBUTION OF THIS POPULATION, ESPECIALLY THAT IT IS NORMAL!What is the probability that a randomly selected individual has a value of 20 or more?
b.ASSUME THE POPULATION IS SYMMETRIC,what is the probability that a randomly selected individual has a value less than 10 or greater than 30?
c. What is the largest possible measurement in this population if we know the minimum is 5?
d. Since the mean=median here, does that imply the distribution is normal? If no, sketch a distribution for which mean=median and it isn't normal.
