Refer to the indicated data set in Appendix B.
a. Construct a histogram to determine whether the data set has a normal distribution.
b. Find the sample mean and sample standard deviation s.
c. Use the sample mean as an estimate of the population mean µ, use the sample standard deviation as an estimate of the population standard deviation σ, and use the methods of this section to find the indicated probability.
Use the combined list of 100 weights of M&M plain candies listed in Data Set 11, and estimate the probability of randomly selecting one M&M candy and getting one with a weight greater than 1.000 g.
