Question

Is each of the following scenarios a binomial setting? If not, explain why.

a) Honda motorcycles pulls one motorcycle off the assembly line each hour to conduct a thorough quality control inspection. One variable recorded is the total number of visual defects to the finish (scratches, imperfections, etc.).
b) Mr. Rye buys one Lotto ticket each week. X is the number of times he wins a cash prize in a year.

Answer 1

binomial is yes/no with p = probability of (e.g.) yes

Mr. Rye's lotto experience could be yes=win, no = not win.

Answer 3

Leslie is doing a science fair project on batteries. She is going to measure X: how many brand new batteries must be purchased and tested before a defective one is found.

Answer 4

This seems to be binomial, but more complicated. The probability that n are tested and none found defective = (1-p)^n, where p is the probability of a defective part, p = # defective/number tested.
You get (1-p)^n by noting you have to succeed in having a good part n times in a row.
