Question 1)

Q.1( 5 marks): The use of R (or Rstudio) is mandatory for this question. Consider two data sets given below: dataset 1: The calories for 20 brands of veggie dogs. 40 45 45 45 50 50 55 57 60 60 70 80 80 81 90 95 100 100 110 190 dataset 2: The calories for 20 brands of beef hot dogs. 111 131 132 135 139 141 148 149 149 152 153 157 158 175 176 181 184 186 190 190 The R code below uses the variable veggiecal to store the dataset 1, while beefcal is used to store dataset 2. dataset 1: veggiecal=c ( 40, 45, 45, 45, 50, 50, 55, 57, 60, 60, 70, 80, 80, 81, 90, 95, 100, 100, 110, 190) dataset 2: beefcal=c( 111, 131, 132, 135, 139, 141, 148, 149, 149, 152, 153, 157, 158, 175, 176, 181, 184, 186, 190, 190) Important Note: Student should use R (or Rstudio) to answer parts (a)-(d). For each part of these, a full answer should comprise the R code, the R output and the comment of the R output. (a) (1.50 mark) Make a five-number summary of the veggie dog calories. Should any of the calorie counts for the veggie hot dogs be classified as outliers? Explain. (b) (1.50 mark) Make a modified boxplot for the veggie dog data. In which quarter - the first, second, third, or fourth - are the data most concentrated? most spreat out ? (c) (0.50 mark) Add a modified boxplot for the beef hot dog calories next to your display in (b). (d) (1.50 mark) Based on your displays in (c), compare the distributions of calories for beef dogs and veggie dogs. 1
