Objective The objective of this assignment is to assess the students on their skills in implementing Monte Carlo simulation models. What is expected? Determine point estimators to the answers for the following problems (Problem 1 to 5) using Monte Carlo method. Use Microsoft Excel with a sample size of 1000 . Problem 3 Estimate the value of the integral 1x2arctan(x)dx Note: The arctangent function of x,arctan(x), is the inverse function of the tangent function of x. In Excel, the function is ATAN (https://support.microsoft.com/en-us/office/atan-function-50746fa8630a406b81d04a2aed395543)
