2. The confidence level is sometimes called the "capture rate." Explain why this is an appropriate term. 3. An insect ecologist reports a 95% confidence interval for the mean length of full-grown aquatic larvae of the Phantom Midge Chaoborus albatus to be 6.9 to 8.5 mm, based on a sample of 9 individual larvae. (a) What are the point estimate and margin of error associated with this confidence interval? (b) The ecologist stated that "all necessary conditions for constructing this confidence interval were met." What does this tell you about his methods and about the population of insect larvae? (c) If the ecologist had reported a 99% confidence interval instead of a 95% interval, how would it have been different? Explain (d) The ecologist was unhappy with how wide this interval was. What should he do to produce a narrower interval with the same level of confidence? Explain
