Biting an unpopped kernel of popcorn hurts! As an experiment, a self-confessed connoisseur of

cheap popcorn carefully counted 773 kernels and put them in a popper. After popping, the unpopped

kernels were counted. There were 86. (a) Construct a 90 percent confidence interval for the proportion

of all kernels that would not pop. (b) Check the normality assumption. (c) Try the *Very Quick*

*Rule*. Does it work well here? Why, or why not? (d) Why might this sample not be typical? Any help on how to solve this? I am at a total lost
