1. **State the problem:** We need to find how many values fall into the class interval $60 \leq x < 65$ from the given data set. 2. **Understand the class interval:** The class includes the lower limit 60 but excludes the upper limit 65. So, values must satisfy $60 \leq x < 65$. 3. **List all data values:** The data set is: $$\begin{matrix} 47.29 & 34.89 & 54.48 & 66.54 \\ 44.9 & 39.62 & 51.35 & 54.25 \\ 58.65 & 39.64 & 44.46 & 49.11 \\ 49.17 & 47.28 & 49.19 & 54.92 \\ 60.57 & 57.6 & 49.82 & 61.2 \\ 34.49 & 47.14 & 70.51 & 52.88 \\ 59.29 & 54.66 & 67.52 & 52.55 \\ 60.08 & 52.5 & 47.14 & 48.4 \\ 60.74 & 53.64 & 49.78 & 60 \\ 53.54 & 60.79 & 44.74 & 65 \end{matrix}$$ 4. **Identify values in the class $60 \leq x < 65$:** - 60.57 (row 5) - 61.2 (row 5) - 60.08 (row 8) - 60.74 (row 9) - 60 (row 9) - 60.79 (row 10) Note: 65 is not included because the upper limit is excluded. 5. **Count the values:** There are 6 values in the class interval $60 \leq x < 65$. **Final answer:** There are **6** values in the class 60-64.99.
