Question

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). Click the icon to view the data a. Find the probability of getting exactly 7 peas with green pods. More Info (Type an integer or a decimal.) b. Find the probability of getting 7 or more peas with green pods. (Type an integer or a decimal.) Probabilities of Numbers of Peas with Green Pods Among 8 Offspring Peas x (Number of 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)? 0+ 0+ 0.008 0.016 0.099 0.214 0.272 0.287 0.104 O The result from part (b) O The result from part (a) 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. 0 A. O B. ° C. 0 D. No, since the appropriate probability is less than 0.05, it is not an unusually high number No, since the appropriate probability is greater than 0.05, it is not an unusually high number Yes, since the appropriate probability is greater than 0.05, it is an unusually high number Yes, since the appropriate probability is less than 0.05, it is an unusually high number 4 6 8 PrintDone

Explanation / Answer

Answer to the questions is as follows:

a. P(X=7) = .287

b. P(X>=7) = P(X=7,8) = .287+.104 = .391

c. Since only a contains P(X=7), which will help us if getting 7 is unsuaully high number, 2nd option is right

d. Since .287 is way higher than .05, it is not a unsuaully high number. B option is right. If an event' probabilty is less than .05 ,then it' unusual
