Each question requires the use of MINITAB to solve. Please submit your work as a WORD or similar document. You can prepare this by cutting and pasting the results generated in MINITAB to such a document. Then you can edit that file with any required explanations (such as for part b of each question).Then just print that file as your submission.
1. Consider the data in problem 2.38 on page 63. This data consists of the cost of electricity during July 2013 for a random sample of 50 one-bedroom apartments in the New York City area. It is included in the data file, UTILITY.
a) Using this data, construct a 95% confidence interval for the population mean cost of electricity for such apartments in July 2013.
b) Briefly explain the meaning of this interval.
c) What is the margin of error when estimating the population mean cost of electricity during 2013 for one-bedroom apartments in that large city?
d) Do you think that the results in a, b, and c, could also be applied to other large cities throughout the U. S.? In other words, do these results generalize to other cities? Explain why or why not.
