For the following​ event, state whether you think the difference between what occurred and what you would expect by chance is statistically significant. Explain.   Tenwinners of the Power Ball lottery in a row bought their tickets at the same​ 7-Eleven store.   Choose the correct answer below.     A. It is significant because, one winner is​ unlikely, two winners is very​ unlikely, and 10 winners is certainly below a 0.01 probability level.   B. It is significant because, one winner is​ unlikely, two winners is very​ unlikely, and 10 winners is certainly above a 0.05 probability level.   C. It is not significant because, in 10 lotteries there are 10 winners.   D. It is not significant because, the difference between the expected number​ winners, 10​, and the actual number of​ winners, 10​, is zero.
