2. In Excel: A1 = 95 A2 = 95 A3 = 80 A4 = 0 =IF(A1<A2),”T”,”F”)

3. In Excel: A1 = 95 A2 = 95 A3 = 80 A4 = 0 =IF(A1<A2),”T”,”F”) 1. T 2. F CORRECT

4. In Excel: A1 = 95 A2 = 95 A3 = 80 A4 = 0 =IF(AND(A3 0),”T”,”F”)

5. In Excel: A1 = 95 A2 = 95 A3 = 80 A4 = 0 =IF(AND(A3 0),”T”,”F”) 1. T 2. F CORRECT

6. In Excel: A1 = 95 A2 = 95 A3 = 80 A4 = 0 =IF(OR(A1<>A2,A4<=0),”T”,”F”)

7. In Excel: A1 = 95 A2 = 95 A3 = 80 A4 = 0 =IF(OR(A1<>A2,A4<=0),”T”,”F”) 1. T CORRECT 2. F

8. In Excel: A1 = 95 A2 = 95 A3 = 80 A4 = 0 =IF(AND(OR(A2 =A3),”T”,”F”)

9. In Excel: A1 = 95 A2 = 95 A3 = 80 A4 = 0 =IF(AND(OR(A2 =A3),”T”,”F”) 1. T CORRECT 2. F

10. Assuming 8000 is the population in 1970, 9000 is the population in 1978, use linear interpolation to estimate the population in 1974: 8200 8250 8400 8500 8600 8750

11. Assuming 8000 is the population in 1970, 9000 is the population in 1978, use linear interpolation to estimate the population in 1974: 8200 8250 8400 8500 CORRECT 8600 8750

12. Other Excel subjects to know: Variables in Excel are kept in cells, addressed by cell addresses (not names as in Matlab) Like Matlab, Excel has a built-in IF statement Excel simulates loops by multiple rows
