Find the Requested Value $\begin{array} { l l l l l } 5.2 & 3.4 & 2.9 & 5.3 & 3.0 \\4.0 & 5.2 & 5.2 & 3.2 & 4.7 \\3.2 & 3.5 & 4.8 & 4.0 & 5.1\end{array}$

Find the requested value.
-Physiologists often use the forced vital capacity as a way to assess a person's ability to move air in and out of their lungs. A researcher wishes to estimate the forced vital capacity of people suffering From asthma. A random sample of 15 asthmatics yields the following data on forced vital capacity,
In liters.
$\begin{array} { l l l l l } 5.2 & 3.4 & 2.9 & 5.3 & 3.0 \\4.0 & 5.2 & 5.2 & 3.2 & 4.7 \\3.2 & 3.5 & 4.8 & 4.0 & 5.1\end{array}$
Use the data to obtain a point estimate of the mean forced vital capacity for all asthmatics.

A) 4.18 liters
B) 4.32 liters
C) 4.27 liters
D) 4.10 liters
