Questions 28-29 refer to the following:
A hypothesis is conducted to see if a new algorithm is faster than an old one. Eight problems are solved twice, the first time using the old algorithm and the second time using the new algorithm. Of interest is the average decrease in time. The difference data ( old-new ) is calculated
