Elizа hаd а lоng cоmmute tо work each day and she was always worried about running late. When it came to distance, both drives were the same number of miles from her home, but one of them had a few more stoplights on her way. She wanted to find the most consistent route so she could know exactly how long it would take her to go to work each day. She decided to travel each route 25 times and recorded how long it took each time to make an informed decision. On her 25 trips using route A, she took an average of 40 minutes with a standard deviation of 3.1 minutes. On her 25 trips using route B, she took an average of 40 minutes with a standard deviation of 4.6 minutes. Assume the commute times using both routes are normally distributed. Use this information to carry out the appropriate hypothesis test at the
