Basic statistics

In this assignment, you will continue to collect data for another 5–10 days for the data collection below. Write a paper (2- to 3-page, typed Word document) including all of the following content:

• Recalculate      the mean (old mean = 419.33), standard deviation (old SD = 47.98 minutes),      and variance (old variance = 2302.05).
• Is your      mean increasing or decreasing?
• Explain the      effects of the larger sample size in relation to your data.
• Do you      think the current sample you have is enough to draw an accurate      conclusion, or do you need a larger sample? 
• What      conclusions can you draw from comparing both sets of data?

The collected data attached is the amount of minutes slept each day for a month: (you need to add 5-10 more days of data)
