Consider the hourly pedestrian count data collected at the Melbourne Central station in Melbourne over the one-month period in March 2022. This dataset is given as a CSV le, named "MeleeutPedCutMur-ch2022.csv". 1.1) Plot the histogram for the count data. Comment on the shape. How many modes can be observed in the data? 1.2) Fit a single Gaussian model Nw, 0'2) to the distribution of the data, where u is the mean and a" is the standard deviation of the Gaussian distribution. Find the maximum likelihood estimate (MLE) of the parameters, i.e., the mean u and the standard deviation 0\". Plot the obtained (single Gaussian) density distribution along with the histogram on the same graph. 1.3) Fit a mixture of Guussiuus model to the distribution of the data using number of Guussiuus equal to 4 (four). Use R programming to perform this
