Question: How long does it take to travel to work Monday through until Friday for 10 days?

Monday = 30 + 35 /2 = 65/2 = 32.5 or 32 ½ or 0.10485
Tuesday = 35 + 25 /2 = 60/2 = 30 or 0.09675
Wednesday = 30 + 30 = 60/2 = 30 or 0.09675
Thursday = 25 + 30 /2 = 55/2 = 27.5 or 27 ½ or 0.0887
Friday = 35 + 35 = 70 /2 = 35 or 0.1129

Based on an additional 5 days:
Monday = 20
Tuesday = 30
Wednesday = 20
Thursday = 25
Friday = 20

Additional Questions:
Is the larger sample changing anything?
Is your mean increasing or decreasing?
Do you think the current sample you have is enough to paint an accurate picture, or do you need a much larger sample?
