Frequency Distribution

How long does it take to travel to work Monday thru 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 Using Excel, prepare a frequency distribution from the data above. Calculate the Standard Deviation of your data. Is this a normal distribution? What are the implications?

Sample

How long does it take to travel to work Monday thru 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 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?
