Answer

Answer:

The monthly salary of Shenika is less spread out than the monthly salary of Clarissa.

Explanation:

Step1: Understand standard - deviation concept

Standard deviation measures spread.

Step2: Compare standard deviations

Shenika's std dev is 7.67, Clarissa's is 12.53. Since 7.67 < 12.53, Shenika's salary is less spread out.
