Frequency Distributions and Sampling..

The databelow is how many minutes that I have read each day for 15 days.

Compare the data from the first 10 days to the last 5 days

20, 10, 17, 20, 60, 0, 30, 0, 0, 0, / 15, 15, 30, 25, 18
Is the larger sample changing anything?

Is your meanincreasing 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?

Now using Excel, prepare a frequency distributionfrom the following data

20, 10, 17, 20, 60, 0, 30, 0, 0, 0

Calculate the Standard Deviationof your data.

Is this a normal distribution?

What are the implications?

Thank you!

Hi,
Herewith I have attached two document.
