Problem 5.75

Refer to Exercises 5.6, 5.24, and 5.50. Suppose that a radioactive particle is randomly located in a square with sides of unit length. A reasonable model for the joint density function for Y1 and Y2 is f (y1, y2) = $ 1, 0 y1 1, 0 y2 1, 0, elsewhere. a What is E(Y1 Y2)? b What is E(Y1Y2)? c What is E(Y 2 1 + Y 2 2 )? d What is V(Y1Y2)?a What are E(Y1 + Y2) and V(Y1 + Y2)? b What is P(Y1 Y2 > 3)? c What is P(Y1 Y2 < 3)? d What are E(Y1 Y2) and V(Y1 Y2)? e What do you notice about V(Y1 + Y2) and V(Y1 Y2)?

STAT 110: Notes for Week of 10/25/16  Chapter 21 o This section will focus on interpreting data and inferential statistics (making inferences about a population based on data from a population sample). o The sample proportion probably is not equal to the parameter.  Sample proportion: p = (# of successes/n)  n = number of subjects in the sample o The sample mean is never equal to the population mean. o Since the sample proportion is probably not equal to the parameter, we will take a confidence interval (sample proportion +/- the margin of error) to make a more confident statement about the data. o Sample distribution: the distributio
