Answer:

Swap codes in line 7 and 8

Explanation:

The code segment below

Line 1: count ← 0

Line 2: sum ← 0

Line 3: FOR EACH value IN numbers

Line 4: {

Line 5: count ← count + 1

Line 6: sum ← sum + value

Line 7: average ← sum / count

Line 8: }

Line 9: DISPLAY (average)

The above code will make the program translator calculate the average value at each iteration.

This will take a longer time to execute and also means more instructions for the program translator.

Swapping line 7 and 8 will reduce the number of instructions to execute. This will have an instant effect on the time taken to execute the program.

Swapping line 7 and 8 means that, the program translator will only calculate the average after it must have finished calculating the sum of the values in the iteration statement.
