Kindly provide me the answer of the following question.
" The mean response on JetBlue was 6.1 (sd = 0.88) and
the mean response on American Airlines was 4.86 (sd = 1.61). Is there enough evidence from
the sample to conclude that users think booking a flight on American Airlines is more difficult
than on JetBlue? What is the likely range of the difference between mean ratings using a 90%
level of confidence?"
