The data set below represents the weights (kg) of high school seniors before graduation. Begin with a lower-class limit of 45 kg and use a class width of 10 kg to construct a frequency distribution. Can we conclude that the distribution appears to be normal?
Weights (kg):
$\text{48, 55, 72, 68, 90, 85, 60, 77, 52, 95, 58, 49, 63, 80, 88, 74, 69, 50, 92, 66, 76, 59, 54, 79, 82, 70, 56, 84, 64}$

• A. Yes, the distribution appears normal with a slight skew.
• B. No, the distribution does not appear normal.
• C. It cannot be decided without plotting a histogram.
