Answer:
Cherry:
S = 0.01652
standard deviation = 0.128530152
Straw:
S =0.0478
And the standard deviation = 0.218632111
Explanation:
Cherry Jalopies:
variance:
∑ (n1 - median)2
First we calcualte the median:
(0.16 + 0.11 - 0.01 + 0.06 + 0.11)/5 = 0.086
Then we calculate the variance:
which is each the sum of return minus the median squared
[tex](0.16-0.086)^{2} +(0.11-0.086)^{2} +(-0.01-0.086)^{2} +(0.06-0.086)^{2} +(0.11-0.086)^{2}[/tex]
S = 0.01652
standard deviation: √S = √0.01652 = 0.128530152
Straw
we do the same procedure:
(0.16+0.23 -0.06+0.06+0.11)/5 = 0.1
Then we do the variance:
0.0478
And the standard deviation:√S = √0.0478 = 0.218632111
