Author:

January 2nd, 2018

A software design company is creating a new, faster search engine. The search engine is clearly faster, but initial tests indicate there is more variation in the time to perform a search. A sample of 16 different searches showed that the standard deviation of the search time was 22 hundredths of a second for the new search engine and 12 hundredths of a second for the current search engine. At the .05 significance level, can we conclude that there is more variation in the search time of the new search engine?
