Here is a histogram of T-cell velocities in vitro (in microns per minute) :
The data represent a random sample of T cells grown in lab conditions. Is it appropriate to compute a 95% for the mean T-cell velocity μ?

A) Yes, despite the clearly skewed data, because the sample size is large enough
B) No, because the data are clearly skewed
C) Yes, because the population of T-cell velocities is most likely approximately Normal
D) No, because the population of T-cell velocities is most likely not Normal
