Students in a large class conducted an experiment on the germination of seeds of saguaro cactus. As part of their experiment, each student planted five seeds in a small cup, kept the cup near a window, and checked every day for germination. The class results on the seventh day after planting were as displayed in the table.

Germinated	not germinated	number of students
0	5	17
1	4	53
2	3	94
3	2	79
4	1	33
5	0	4
		280

A) fit a binomial distribution to the data (round the expected frequencies to one decimal place)

B) Two students were talking, Fran and Bob, all of Fran's seeds had germinated by the seventh day and non of Bob's had. With perspective gained from seeing all 280 students' results, what would you say to Bob? (Hint, can variation among students be explained byt the hypothesis that some of the seeds were good and some were poor, with each student receiving a randomly chosed five seeds?)
