GI'OUQ Proiect -A- MATH 2591for students whose Student ID# ends with even #) As utility company supervisor you have been monitoring the voltage fluctuations from various supply grid locations via the remote sensors. In the past, the mean supply grid voltage was 120 V with some noticeable degree of fluctuations (Standard Deviation: 40V) where the target voltage for the household loads should lie between 110-160 V. The utility company has recently switched to a new sophisticated electricity service provider which claims that voltage fluctuations would be reduced. You have been assigned to ensure that the new service is more stable. The data in the table (see appendix) gives voltage readings at various supply grid locations. 1. Describe and organize your data and present all findings of a descriptive nature (Part 1 and 2 submissions) 2. Using an appropriate level of significance, conduct a formal hypothesis test to determine whether the utility company's claims are valid (For Part 2 submission only) 3. Make a recommendation based on your findings (For Part 2 submission only). Note: You must attach relevant calculations for any statistics generated manually or by a statistical software at the back of your report
