The above two tables are related to the variable WIND. The first is a regression table with 5-variables predicting the WIND while the second table contains the Summary statistic related to WIND data. Answer the questions (choose the most appropriate answer):

I) If Variable 5 increases by 10 units, according to the table what would be your prediction? (11.11 points)

• a. The WIND will be about 0.27 units
• b. Since Standard Error is 1.3 the WIND will be between 0.27-1.3 and 0.27+1.3 units
• c. No conclusion because R-square is too large
• d. WIND will increase by 0.27 units
• e. None of these

II) If all 5 variables increase by 1 unit, according to the table what would be your prediction? (11.11 points)

• a. The WIND would increase by approximately 14.38 units
• b. The WIND would be approximately 14.38 units
• c. The WIND would be approximately -0.09 units
• d. The WIND would decrease by approximately 0.09 units
• e. None of the above

III) Which two numbers are design to describe the center of the variable WIND? (numbers are rounded) (11.11 points)

• a. 9.3 & 0.23
• b. 9.3 & 1.42
• c. 9.3 &1.3
• d. 9.3 & 9.4
• e. 9.3 & 14.4
