Upload thePollutiondata. Check which of the following six categories ( MANUF, POP, TEMP, WIND, PRECIP-INCHES, and PRECIP-#DAYS) isnegatively correlatedto the SO2 category. Make a scattered plot chart with X representing the most negatively correlated category and Y representing SO2, plot the line and compute the R-square. Answer the questions:

I) What category did you choose for X? (10 points)

• a. MANUF
• b. POP
• c. TEMP
• d. WIND
• e. None of these

II) According to the convention table how would you describe the strength of the relation between the X and Y coordinates? (10 points)

• a. Poor
• b. Decent
• c. Good
• d. Very Good
• e. Excellent

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

• a. MANUF
• b. SO2
• c. CITY
• d. YEAR
• e. None of these

IV) On your chart, there should be two dots at the very top of the chart. Their Y-coordinate are: (10 points)

• a. Between 0 and 30
• b. Between 30 and 70
• c. Between 110 and 150
• d. Between 150 and 200
