A grocery store keeps records of deliveries they receive from suppliers. Their records for watermelons show: mean weight of watermelons is 17 pounds, with a standard deviation of 8 pounds. Assuming watermelon weights are normally distributed, does this make sense?
Explain why or why not

For assuming that our distribution is normal or not we should first find a z score and see that 68% of our data falls within1 standard deviation of the mean. As we find the probability of area between -1.64 to +1.64 is 68.8%. And the curve is showing the property of normal distribution.
So we can say assume that watermelon weights are
normally distributed.
