According to the U.S. Forest Service, adult Karner Blue Butterflies have a mean wingspan of only one inch. An entomologist has seen a few of these butterflies in the field that look bigger than one inch. She speculates that the mean wingspan of Karner Blue Butterflies is bigger than what the U.S. Forest Service is reporting. The entomologist takes a random sample of 20 adult Karner Blue Butterflies to investigate her speculation. Question 7 Subquestions 7.a TBD points Clearly state the hypotheses to be tested. No answer entered. Click above to enter an answer. 7.b TBD points Since we are told that a random sample of 20 adult Karner Blue Butterflies is selected, the first assumption is met. State the remaining assumption, in context, that is checked using the Q-Q plot below.

O Type II Power O Type l 7.d 1 point(s) The entomologist would like to increase the probability of correctly concluding that the mean wingspan has increased. What could she do in the future? take a random sample of 40 butterflies take a random sample of 15 butterflies Save Assignment Terms and Conditions Privacy Policy Contact Us Copyright @ 2015-2019
