Question 127097: Please help me. Thankyou
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?
