Normal Distribution

Let's suppose we analyze a set of 30 data points and it's characteristics of the distribution. Data below should be quantitative.

Part 1

Let's suppose a student views Tik Tok videos over 30 days:

7, 11, 6, 8, 8, 10, 7, 6, 13, 7, 6, 9, 11, 8, 14, 8, 5, 8, 6, 12, 3, 10, 8, 5, 9, 4, 9, 10, 12, 7

Part 2

A visual representation for any axes with appropriate titles and appropriate scale on each axis.

Part 3

1. What is the mean and standard deviation of the set of data?

2. Can the data follow a normal distribution?

3.

a. Does the sample follow a normal distribution. How come it does?

b. If the sample does not follow a normal distribution, why isn't it a normal distribution?

4. How can the survey process be described? What are some sources of possible bias in the sample? How is it a ensured random sample?

5. What kind of set of data can be used in the future? How can it be ensured as an unbiased random

sample?

It would be of gratitude if you could help me with this, thank you.
