By default, your numerical entry is scored as correct if it is within 1% of the correct answer. A rule of thumb is always to enter at least 3 digits for numerical questions.
If the correct answer is 7.08809, which of the following entries would be counted as correct?
7.024
7.09
6.9392
6.9
7.24
7.1519
please explain
To determine which entries would be counted as correct, we need to calculate the range within 1% of the correct answer.
Given that the correct answer is 7.08809:
Lower bound: 7.08809 - (1% * 7.08809) = 7.08809 - 0.0709 = 7.01719.
Upper bound: 7.08809 + (1% * 7.08809) = 7.08809 + 0.0709 = 7.15999.
Now, let's evaluate the given entries:
1. 7.024:
This entry falls within the range of 7.01719 to 7.15999. Therefore, it would be counted as correct.
2. 7.09:
This entry is within the range of 7.01719 to 7.15999. It would also be counted as correct.
3. 6.9392:
This entry is below the lower bound of the acceptable range. Hence, it would not be counted as correct.
4. 6.9:
Similar to the previous entry, this is below the lower bound of the acceptable range and would not be counted as correct.
5. 7.24:
This entry exceeds the upper bound of the acceptable range. Therefore, it would not be counted as correct.
6. 7.1519:
This entry falls within the range of 7.01719 to 7.15999. As a result, it would also be counted as correct.
So, out of the given entries, 7.024, 7.09, and 7.1519 would be considered correct since they fall within 1% of the correct answer.
