Answer:
The score of 92 on a test with a mean of 71 and a standard deviation of 15 is better.
Step-by-step explanation:
To find which score corresponds to the higher relative position, we find the Z-score of each score.
The z-score, which measures how many standard deviation a measure is above or below the mean, is given by the following formula:
In which X is the score, is the mean and is the standard deviation.
A score of 92 on a test with a mean of 71 and a standard deviation of 15.
So
A score of 688 on a test with a mean of 493 and a standard deviation of 150.
So
Which is better?
Due to the higher z-score, the score of 92 on a test with a mean of 71 and a standard deviation of 15 is better.
X= 2.14 i think but that’s just what i think it is according to the calculator
The digit in the thousands place is 1
