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 28 times and recorded how long it took each time to make an informed decision. On her 28 trips using route A, she took an average of 40 minutes with a standard deviation of 5.4 minutes. On her 28 trips using route B, she took an average of 40 minutes with a standard deviation of 5.9 minutes. Assume the commute times using both routes are normally distributed. Use this information to carry out the appropriate hypothesis test at the

Image Description The line graph is titled “Cardiovascular Disease Prevalence in US Adults (Age 18 or Older) from 1997 to 2009.“ The x-axis is titled “Year,” and its values start at ’97, increasing by one year each time, and end at ’09. The y-axis is titled “Rate (per 1,000),” and its values start at 0, increase by one hundred each time, and end at 600. The first line is labeled “Stroke” and starts at 45 in 1997. The line remains steady until 2009. The second line is labeled “Hypertension” and starts at 110 in 1997. It also remains steady until 2009. The third line is labeled “Heart Disease (coronary)” and starts at 230 in 1997. The line remains mostly steady (with some slight increases and decreases) until 2009. The fourth line is labeled “Heart Disease (all types).” It starts at 390 in 1997 and increases to 490 in 2009.
