Homework/study question for review:

UploadUS crimedata: https://www.limes.one/Content/DataFiles/US_CRime.txt and compare the robbery counts for the states ofCalifornia,New MexicoandWashington. Your job is to identify which of the two states ismost correlatedtoNew Mexico. Make scattered plot chart withX representing New Mexicoand Y representing that state in question, plot the line and compute the R-square. Answer the questions:

I) What are the approximate slope and the R-squares on your chart? (10 points)

• a. 0.3241 & 0.7849
• b. 2.4216 & 0.7849
• c. 0.0176 & 0.5362
• d. 13.735 & 0.8151
• e. None of the above

II) What is the approximate Y-intercept and what is its interpretation? (10 points)

• a. 59.044 & For every year with zero crime the robbery counts increase by 59.044
• b. 861.55 & When there are zero robbery counts in New Mexico we expect to see about 861.55 robbery counts in Washington
• c. 59.044 & When there are zero robbery counts in Washington we expect to see about 59.044 robbery counts in New Mexico
• d. 861.55 & As crime counts increases in New Mexico so does the counts in Washington.
• e. None of the above

III) What does each dot represent? (10 points)

• a. The comparison in robbery counts between Washington and New Mexico
• b. A year
• c. A state
• d. A crime
• e. None of the above

IV) The highest dot on your chart has (approximately) the following Y-coordinate (10 points)

• a. 7178
• b. 2329
• c. 7464
• d. 2966
• e. None of the above
