Standard Normal Distribution: Videos & Practice Problems

A researcher records the weights (in units of grams) of $16$ apples from an orchard: $120$, $122$, $125$, $127$, $129$, $130$, $132$, $133$, $135$, $137$, $139$, $140$, $142$, $144$, $146$, and $148$. The orchard claims that the weights are normally distributed with a mean of $135$ grams and a standard deviation of $8$ grams. Draw a frequency histogram to display these data points using $5$ classes. Does the data appear to be normally distributed?
