Question: To hunt flying insects, bats emit high-frequency sounds and then listen for their echoes. One interesting question is: how far apart are the bat and the insect when the bat first senses that the insect is there? The following table lists bat-to-insect detection distances for 11 catches. Find the 95% confidence interval for μ, the true bat-to-insect detection distance. Is the assumption that the bat-to-insect detection distances are normally distributed tenable?
