Question 5) Use R to compute statistics and plots for this question. A study of water usage (in litres per day) involved a random sample of twenty five households. The data are found in the file WATERUSE.txt. (a) For the water usage, compute the following descriptive statistics: mean, standard deviation, median, first quartile, third quartile. Remark: When using the function quantile use the argument type =6 to compute the quartiles. (b) Give the boxplot for the water usage. Does the plot suggest that there are outliers? (c) Produce a quantile-quantile for the household water use. Is it reasonable to assume that water usage is normally distributed? *WATERUSE - Notepad File Edit Format View water use 1316130613291328132413411320134212901322130313071301132213391322135213171310133413351344131113481369
