Answer: -11
Explanation: Once the number scale descends into the negatives, the numbers closest to zero are the biggest while those farther along the line are smaller. This is because it is negative, but if both numbers were positive, the answer would be three because it is of lesser value than positive 11. But in this case, it’s the opposite.

Step-by-step explanation:
Z-score
In a set with mean and standard deviation , the zscore of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this problem, we have that:
He needs to score below what value in order to advance to the next round?
Below the 20th percentile, so below the value of X when Z has a pvalue of 0.20. So it is X when
