... (based on Auntie Annie pretzel survey). 10 children come to sit on Santa’s lap. He asks them if they have been good or bad. a) Can this be considered a binomial experiment? Why or why not? b) What is the probability that all children say they were good? c) What is the probability that at least one c ...

Hence, the area in the left tail is 0.0250 and the area in the right tail is 0.0250. Step 3: Identify the test statistic. Because both samples are large (greater than 30) the z distrib ...
