3) Elsie, a librarian wants to investigate the length of time, 7 minutes, that people spent in her library on a particular day. Elsie's data for 160 people who visited the library on that particular day is shown in the following table. T (minutes) Frequency 0≤T<20 20 ≤ T <40 40 ≤ T < 60 50 62 0 10 20 30 Elsie assumes her data to be representative of future visitors to the library. The following box and whisker diagram shows the times, in minutes, that the 10 visitors spent in the library. 60 ≤ T < 80 14 40 50 60 70 80 90 T (minutes) a) State whether the variable T is discrete or continuous. b) Find the value of k. c) i) Write down the modal class. ii) Write down the mid-interval value for this class 80 ≤ T < 100 8 100 option Elsie believes the box and whisker diagram indicates that the times spent in the library are not normally distributed.
