Good evening,

I need help in finding the solutions and the way to solve the following:

For the following data: (Ordered) 3 4 5 8 8 10 12 12 20 22

a) Calculate

1) the mean or average 6) the range

2) the median, 7) the interquartile range

3) the mode 8) the variance

4) the mean range, 9) the standard deviation

5) the mean axis, 10) the coefficient of variation

b) Make a Graphic Box Plot (Box and Wisker)

c) Determine the values of the border or near the atypical numbers (outliers)

d) Answer whether or not there are outliers. If there are, what are they?

e) Determine how many standard deviations the number 8 is from its mean.

f) If I had to estimate the standard deviation, what would it be?

g) According to Tchevyshev's Theorem, between which pair of values must be at least 75% of the data.

Please, I would appreciate it if you could help me understand this exercise by showing me step-by-step what to do.

Thank you in advance for your help.
