4. faithful is a built-in R data frame giving waiting time between eruptions and the duration of the eruption for the Old Faithful geyser in Yellowstone National Park, Wyoming, USA. We are interested in some descriptive statistics related to the eruptions column of faithful. We can access the data directly by using the assignment x <- faithful$eruptions. (In R use ?faithful for info on this dataset.) Remember: X <- faithful$eruptions a.Calculate the sample median of x. 3.487783 b. Using the R quantile function, find the .34 quantile of x. (34th percentile) 3.487783 c. Calculate the interquartile range of x using R. 1.302728 d. Calculate the sample mean of x. 1.141371 e. Calculate a 2/272 trimmed mean for x. 3.487207 f. Calculate the sample variance of x. 500.2975 g. Calculate the sample standard deviation of x. .954 h. What proportion of the x values are within 1.47 sample standard deviations from the sample mean 5 i. Calculate the maximum value of x. .014 j. What number do you get if you add up the sum of the values in x?
