In the 1992 presidential election, Alaska's 40 election districts averaged 2121 votes per district for President Clinton. The standard deviation was 553. (There are only 40 election districts in Alaska.) The distribution of the votes per district for President Clinton was bell-shaped. Let X = number of votes for President Clinton for an election district. (Source: The World Almanac and Book of Facts) Round all answers except part e. to 4 decimal places.
a. What is the distribution of X? X ~ N(,)
c. Find the
d. Find the probability that a randomly selected district had between 2306 and 2476 votes for President Clinton.
e. Find the third

- A popular theory is that presidential candidates have an advantage if they are taller than their main opponents. Listed are heights (in centimeters) of randomly selected presidents along with the heights of their main opponents.

- Pull up the StatCrunch data set titled Bear Measurements Data Set created by Imazaleski. Use the values for the chest and age of the bears to answer the questions below. To make sure we understand the data, keep the following in mind: Age is the bear's age in months Month is the month the measurements were taken Head Length is the length of the head in inches Head Width is the width of the head in inches Length is the length of the body in inches data. Neck is the distance around the neck in inches Chest is the distance around the chest in inches Weight is in pounds a. What is the value of r (correlation coefficient)? Is there linear correlation between the 2 variables? Explain. b. Identify the dependent variable and the independent variable. c. What is the equation of the least-squares regression line? d.
