Answer :
Final answer:
Salma scored lower relative to her population.
Explanation:
To find the z-scores of Latoya's performance on the English test and Salma's performance on the German test, we will use the formula:
z = (x - μ) / σ
where z is the z-score, x is the data point, μ is the population mean, and σ is the standard deviation.
For Latoya's score on the English test:
z = (580 - 639) / 22 = -2.68
For Salma's score on the German test:
z = (495 - 533) / 18 = -2.11
Now, let's compare the z-scores to determine who scored lower relative to their population:
Latoya's z-score is -2.68, which means her score is 2.68 standard deviations below the mean of the English test scores.
Salma's z-score is -2.11, which means her score is 2.11 standard deviations below the mean of the German test scores.
Since a lower z-score indicates a lower score relative to the population, we can conclude that Salma scored lower relative to her population.
