Question

10. The accompanying table describes results from eight offspring peas. The random variable x represents the number of offspring peas with green pods. Complete parts​ (a) through​ (d).

Probabilities of Numbers of Peas with Green Pods Among 8 Offspring Peas
x​ (Number of Peas with Green​ Pods)	​P(x)
0	​0+
1	​0+
2	0.008
3	0.017
4	0.071
5	0.192
6	0.355
7	0.253
8	0.104

A. Find the probability of getting exactly 7 peas with green pods.

B. Find the probability of getting 7 or more peas with green pods.

C.Which probability is relevant for determining whether 7 is an unusually high number of peas with green​ pods, the result from part​ (a) or part​ (b)?

D.Is 7 an unusually high number of peas with green​ pods? Why or why​ not? Use 0.05 as the threshold for an unusual event.
