b. the first quartile is $1,876.40.
c. the third quartile is $1,876.40.
d. the interquartile range is $1,876.40.

Explanation:

• The first quartile ($Q_1$) is the value below which 25% of the data lies.
• The third quartile ($Q_3$) is the value below which 75% of the data lies.
• If 75% of the wages are higher than $1,876.40$, then 25% of the wages are lower than or equal to $1,876.40$. This means $1,876.40$ is the first quartile ($Q_1$).

Answer:

B. The first quartile is $1,876.40$.
