Question: #2) An electric company is creating new equipment that is sensitive to frequent lightening strikes. The company claims that lightening strikes 2 or less days per 100 days in a certain area. After 650 days of collected sample data, we would like to demonstrate that lightening strikes 2 or less days per 100 days. By doing so, we can give the OK to proceed with the manufacturing of the new equipment. Can we support the claim that lightening strikes 2 or less days per 100 days. Use a Z-test at alpha = 0.01 .

Sample days= 650 days

Total days of lighting strikes in 650 days = 11 days with lightening strikes.

Mean number of days with lightening strikes per 100 days = 1.692 days
