Please solve in R

Complete at least one part of one of the following problems. If you use to solve, please post your answers with code. Consider the following sample. 28, 33, 22, 35, 31 The sample is made up of lID random variables drawn from normal distribution having mean Hand variance o?. (So the random variable X-NG NO?). We would like to estimate the multivariate parameter using Maximum Likelihood estimation (MLE). This is a multivariate estimation problem where the parameter that needs to be estimated is a two dimensional vector made up of the mean and variance 8. Problem 2. To find the MLE, we will use a root finding technique. What function will we be finding the root of? Again, what are the unknown variables in the function that we will be maximizing with respect to?
