I am in need of assistance on this assignment. Thank you very much!

Fundamental Toys Inc. is looking to expand its stock portfolio. You receive an urgent text message from Bob. An email message: As you know, the company has had a very profitable quarter, and management has decided to accrue a liability previously disclosed concerning a hazardous waste site cleanup. I need to provide financial accounting with an accrual amount for the quarter's financial reporting. Management has decided to accrue at the lower range of the 68% confidence interval and has asked me to provide the dollar amount. I'm giving you this assignment. Here's what you need to know: Environmental Engineering has provided the following cleanup forecast with probabilities in parentheses (in thousands of dollars): Low estimate Most likely High estimate $15,000 (0.20) $20,000 (0.70) $25,000 (0.10) Here's what I need from you: Provide the accrual amount for the quarterly 10Q statement. Submit your analysis in my drop box by the date to be specified. Note from Professor: Activity 1: First you need to determine the expected return which is, as we know, equal to the sum of the products of individual probability time the possible outcome (since we know the possible outcomes and their probabilities, we can determine this expected return). This expected return will be used by you as the mean value. Then you will calculate the variance as the sum of every ((outcome -mean)^2)* probability for that specific outcome. Once you have the variance you can calculate the standard deviation expressed in dollars. The required confidence interval will be located with plus or minus (a specific number) of standard deviations around the mean Fundamental Toys Inc. is looking to expand its stock portfolio.
