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. (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.) 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)? The result from part (a) The result from part (b) 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. No, since the appropriate probability is greater than 0.05, it is not an unusually high number. No, since the appropriate probability is less than 0.05, it is not an unusually high number. Yes, since the appropriate probability is less than 0.05, it is an unusually high number. Yes, since the appropriate probability is greater than 0.05, it is an unusually high number.

Explanation / Answer

b) Probability of 7 or higher is

P(7) + P(8)

so 0.311+0.089 = 0.4

c) There is no part a in the given question to make the comparison

d) yes , as the probability for 7 is as high as 0.311 and is greater than 0.05 , so this is unusually a high number

Till 4 , the probabilities are quite close to 0 , so is 8

and probabilities of 5 , 6 and 7 are relatively high , with prob(7) being the highest
