question 5

Multiple Choice

Use computer software to find the multiple regression equation. Can the equation be used for prediction?
-FPEA, the Farm Production Enhancement Agency, regressed corn output against acreage, rainfall, and a trend line. The trend line is proxy for technological advancement in farming from improved pest control, fertilization,
Land management, and farming implements.

• A) CORNPROD \(= - 21.1 + 0.036 \mathrm { ACRES } + 2.62 \mathrm { RAIN } + 27.6 \mathrm { TREND }\); No, because the P-value is low
• B) CORNPROD \(= - 0.9 + 1.68 \mathrm { ACRES } + 0.79 \mathrm { RAIN } + 10.2 \mathrm { TREND }\); Yes, because the adjusted \(\mathrm { R } 2\) is high
• C) CORNPROD \(= - 16.3 + 2.6 \mathrm { ACRES } + 3.9 \mathrm { RAIN } + 21.3 \mathrm { TREND }\); Yes, because the the \(\mathrm { R } ^ { 2 }\) is high
• D) CORNPROD \(= - 21.1 + 0.036 \mathrm { ACRES } + 2.62 \mathrm { RAIN } + 27.6 \mathrm { TREND }\); Yes, because the \(\mathrm { R } ^ { 2 }\) is high
