Project #31923 - Sampling

For this module, continue to collect data for five days.

Day 1 slept-5 hours

day 2 slept -5 hours

day 3 slept- 5.25 hours

day 4 slept- 6 hours

day5 slept 5 hours

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?

I am attaching the first part of the project where I kept a data of 10 days of how long i slept for this study. The 5 days above are to be added.
