An InsuranceQuotes.com survey indicates that there is a 0.08 probability that a randomly selected person has had a holiday package stolen from their front door.*  If you talk to 9 random people, find the probability that at least one of them has had a holiday package stolen from their front door.  Show all work.  Round your final answer to three decimal places. *Problem adapted from book and based on real data.

A bag contains 4 brown and 11 green M&Ms.  You randomly select two M&Ms from the bag without replacement (you eat each M&M after choosing it). Find the probability that the first is green and the second is brown.  Write your final answer as decimal, rounded to three decimal places.  Show all work.

Is there a relationship between the heights of fathers and their firstborn biological daughters?  To answer this, I randomly chose 11 measurements from an actual data set*.  The linear correlation coefficient between the height of the father and the height of the firstborn daughter is 0.431. The mean height of the fathers was 69.1 inches and the mean height of the daughters was 65.0 inches.  The linear regression equation for the data is Daughter = 32.7+0.47(Father), using Daughter and Father instead of y and x. Is there sufficient evidence of a linear correlation between the height of a father and his firstborn biological daughter?  Use a 0.05 significance level and thoroughly support your answer using the table below.  Find the best prediction of the height of a daughter if the father is 70 inches tall.  Do not round. *Actual data listed in the your textbook from the journal of Francis Galton (1822-1911), initiator of the ideas of standard deviation, regression line and correlation.
