Problem 2.9.23

A random variable has a probability density function f (x) = A/x2 for 2 x 4. (a) What is the value of A? (b) What is the lower quartile of the distribution?

Step-by-Step Solution:
Step 1 of 3

Chapter 2 Notes • Deviation—Given a value y and a data point x then x-­‐y represents how far x deviates from y. o Ex. Given x=10 and y=5. 10 deviates by 5 from 5. • Bar Charts—Display where the length of a bar corresponds to the frequency or number of observations in a category • Pie Charts—Slice is proportional to the amount in each category • Relative Frequency—The proportion and is calculated by relative frequency= # in the class/
