Answer

Explanation:

Step1: Calculate Helena's mean

Sum of Helena's missed - classes: $3 + 3+2 + 2+2 + 3+2 + 4+4 = 29$. Number of courses $n = 10$. Mean $\bar{x}_{Helena}=\frac{29}{10}=2.9$.

Step2: Calculate Juanita's mean

Sum of Juanita's missed - classes: $0 + 8+3 + 1+8 + 4+2 + 4+8 + 9=47$. Number of courses $n = 10$. Mean $\bar{x}_{Juanita}=\frac{47}{10}=4.7$.

Answer:

The mean number for missed classes for Helena was $2.9$. The mean number for missed classes for Juanita was $4.7$.
