Explanation:
![\sum \frac{(x- mean)^2}{n}](https://tex.z-dn.net/?f=%5Csum%20%5Cfrac%7B%28x-%20mean%29%5E2%7D%7Bn%7D)
![\left[\begin{array}{cccc}State&Return&Probability&Weight\\recession&0.2&-0.116&-0.0232\\fail&0.8&0.165&0.132\\Total&&0.049&0.1088\\\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bcccc%7DState%26Return%26Probability%26Weight%5C%5Crecession%260.2%26-0.116%26-0.0232%5C%5Cfail%260.8%260.165%260.132%5C%5CTotal%26%260.049%260.1088%5C%5C%5Cend%7Barray%7D%5Cright%5D)
The mean average return will be 0.1088
( (0.165 - 0.1088)² + (-0.116-0.1088)² ) / 2 =
( 0,00315844 + 0,05053504 ) / 2 = 0,02684674
Now, we calcualate the root:
²√0,02684674 = 0.163849748

Answer: describe the bottom line of the policy changes at the beginning of the memo
Explanation:
The options to the question are:
a. describe the bottom line of the policy changes at the beginning of the memo.
b. include an apology at the end of the memo stating the inconveniences that could be caused due to the new policy.
c. present the rationale for the new policies at the memo's beginning.
d. highlight controversial issues, which could arise after the new policies have been implemented, in the memo.
From the question, we are informed that Rubina is the director of procurement at Baines Corporation and that she plans to send a memo to the employees in her department outlining some changes in the company's personnel policies as she believes that most of the employees will view the changes favorably.
Since she is of the opinion that most of the employees will view the changes favorably, she can describe the bottom line of the policy changes at the beginning of the memo. This is because she believes the memo will get a favourable audience. In a situation whereby she is not sure if it will be favourable, in the begining of the memo, she may have to offer and apology and tell them the rationale behind the memo before going into further details.
