1. Weights measured in grams of randomly selected M&M plain candies:

0.9570.9120.9250.8860.9200.958

0.9150.9140.9470.9390.842

a.The mean weight of the M&M's is _______________

b.The standard deviation of the weight of the M&M's is _____________

c.Assuming the weight of M&M's is normally distributed, what is the range of weights of the middle 68% of M&M's? ___________________

d.What is the range of weights of the middle 95% of M&M's? __________________

Use this range in a meaningful sentence.

e.Explain the likelihood of an M&M candy weighing less than 0.886 grams. Calculate the z-score and use a z-table to find the probability. Diagram this problem with the appropriately shaded bell curve.

Z= _______________

Probability = ___________________
