Inbreeding of tropical wasps. Refer to the Science study of inbreeding in tropical swarm-founding wasps, presented in Exercise 7.139

(p. 389). A sample of 197 wasps, captured, frozen, and subjected to a series of genetic tests, yielded a sample mean inbreeding coefficient of x = .044 with a standard deviation of s = .884. Recall that if the wasp has no tendency to inbreed, the true mean inbreeding coefficient m for the species will equal 0.

a. Test the hypothesis that the true mean inbreeding coefficient m for this species of wasp exceeds 0. Use a = .05.

b. Compare the inference you made in part a with the inference you obtained in Exercise 7.139, using a confidence interval. Do the inferences agree? Explain.
