6) Over the past five years, your investment provided the following percentage returns:

Year	Annual Return
2016	6.785%
2017	3.485%
2018	2.380%
2019	-3.456%
2020	10.260%

Calculate the sample variance: (1/1000 of one percent without % sign, e.g. 12.671, if a negative percentage, -9.56):

7) You purchased shares of a TSX listed company at the cost of $53.40 per share at the beginning of 2017. Over the next four years, the stock had following stock prices and dividends:

Year	Year End Price	Dividends
2017	$55.70	$1.50
2018	$52.40	$1.10
2019	$50.80	$1.00
2020	$57.90	$1.20

Calculate the following statistics: (1/1000 of one percent without % sign, e.g. 12.671, if a negative percentage, -9.56):

1) 2017 percentage return:

2) 2018 percentage return:

3) 2019 percentage return:

4) 2020 percentage return:

5) Arithmetic mean:
