Question:
The measured voltage levels from a generator, as listed in Data Set 13 in Appendix B.
Refer to the indicated data set and determine whether the data have a normal distribution. Assume that this requirement is loose in the sense that the population distribution need not be exactly normal, but it must be a distribution that is roughly bell-shaped.

Data Set 13: Voltage Measurements From a Home All measurements are from the author's home. The voltage measure- ments are from the electricity supplied directly to the home, an inde- pendent Generac generator (model PP 5000), and an uninterruptible power supply (APC model CS 350) connected to the home power supply. STATDISK: Data set name is Voltage. Minitab: Worksheet name is VOLTAGE.MTW. Excel: TI-83/84 Plus: Workbook name is VOLTAGE.XLS. App name is VOLTAGE and the file names are the same as for text files. Text file names: Text file names are VHOME, VGEN, VUPS.
