A pаrticulаr insect cаn infest оrange trees and pоtentially damage the оranges. Joyce, an orange farmer, plans to investigate the number of damaged oranges on insect-infested orange trees on her farm. Suppose the probability is 0.41 that an insect-infested orange tree from the large farm has no more than 77 damaged oranges. Joyce selected a random sample of 3224 insect-infested orange trees from the farm and recorded the number of damaged oranges for each tree in the sample. Joyce plans to use the sample data to investigate whether there is convincing statistical evidence that all insect-infested orange trees from the farm have a mean number of damaged oranges that is fewer than 77. (a) State, in words, the hypotheses for the appropriate test. (b) Why is the condition for normality of the sampling distribution met? Assume all other conditions for inference are met as well. The p-value of Joyce’s test was approximately 0.037 (c) Interpret what the value 0.037 measures in the context of the study. NOTE: Type all answers in the space below.
