Randy is attending film school and one of his projects involves researching the ratingsgiven to movies by critics and viewers. He has selected a random sample of movies andhas recorded the average critic score (X1) and the average viewer score (X2) for eachmovie. The scores were obtained from a website that collates movie reviews and ratingssubmitted by critics and viewers. Randy also recorded the genre (X3) of each movie. Thedata are stored in the file AssignmentData.RData in the data frame movies.df.(a) [3 marks] Create a scatter plot of average critic score against average viewer scorefor comedies, with average viewer score along the x-axis. Make sure to give yourplot a proper descriptive title and appropriate labels for the x and y axes. Describethe relationship between these two variables for comedies

Provide a clearjustification for your answer.(c) [3 marks] For thrillers, test whether the population proportion of movies that havean average viewer score greater than 3.27 is less than 0.5. Clearly state your hypothe-ses, making sure to define any parameters, and use a significance level of α = 3%.Do not use any R functions that are designed to perform hypothesis tests.(d) [4 marks] For dramas, test whether the population mean average viewer score isgreater than the population mean average critic score by more than 0.05.
