Upload US crime data and compare the murder counts for the states of Montana, California and Nevada. Your job is to identify the state that is most correlated to Montana. Make a scattered plot chart with X representing Montana and Y representing the chosen state, plot the line, and compute the R-squared.

Answer the questions:

1) What is the approximate slope and the R-squared on your chart?

a. 46.574 and 1018.1

b. 0.1782 and 1018.1

c. 0.1782 and 46.574

d. -0.0086 and 0.012

e. None of the above

2) What is the approximate Y-intercept and what is its interpretation?

a. 1018.1, For every year with zero crime the murder count increases by 46.574

b. 0.1782, If we observe zero crimes in Montana we expect 0.1782 crimes in California

c. 0.012, Murders in these two states are not very much related

d. 46.574, For each observed crime in Montana we expect to see 46.574 crimes in California

e. None of the above

3) What does each dot represent?

a. A year

b. A murder

c. Murder comparison

d. A crime

e. None of the above

4) The highest dot on your chart has (approximately) the following Y-coordinate

a. 1018

b. 48

c. 4096

d. 0.012

e. None of the above
