Moving average tables?

Question

Given the data

t: 1 2 3 4 5 6

x: 6 8 7 8 9 9

Construct the moving average table with N = 3.

Construct a table for single exponential smoothing with 'a = 0.5' ('a' is an alpha sign)

The exponential smoothing is the most important part of this question.

Thank you

Answer 1

For exponential smoothing, I have attached a source, which has an example.

Let alpha=0.5
