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
Data:

Heating cost ($) Square footage
350 2430
280 2410
300 2030
250 2240
310 2350
460 2640
320 2230

Re: Can someone help me get the UCL AND LCL for this problem?

Please remember: We ask that for questions like this, assuming it's homework, that you:
  1. Please try the problem on your own first, and tell us what you have done so far. The more information we have, the better we can help you. Please don't expect quick solutions to your homework. We'll help you get started, exchange ideas, how-to's, etc. but only if you show that you are willing to learn and put in effort as well.
Thank You to Marc for your informative Post and/or Attachment!
