Hey guys i have tried using statcrunch to get this answer for hours and i keep on getting the wrong answer, can someone please help me get the UCL AND LCL of this problem?
Suppose a government department would like to investigate the relationship between the cost of heating a home during the month of February in the Northeast and the home's square footage. The accompanying data set shows a random sample of 10 homes. Construct a 90% confidence interval to estimate the average cost in February to heat a Northeast home that is 2,100 square feet
Heating cost ($) Square footage
