The following are the annual maximum flows in m³/s in the XYZ River for a 52-year period: 1980 1130 3120 2120 1700 2550 8500 3260 3960 2270 1700 1570 2830 2120 2410 2550 1980 2120 2410 2410 1420 1980 2690 3260 1840 2410 1840 3120 3290 3170 1980 4960 2120 2550 4250 1980 4670 1700 2410 4550 2690 2270 5660 5950 3400 3120 2070 1470 2410 3310 3230 3090 What is the sample size? Compute the sample mean, sample median, sample standard deviation and sample range. (iii) Compute the interquartile range (IQR). (iv) Construct a histogram (count as y-axis) and a relative frequency diagram (relative frequency in percentage as y-axis). Use the following class limits: (0,1000], (1000,2000], (2000,3000], (3000,4000], (4000,5000], (5000,6000], (6000,7000], (7000,8000], (8000,9000], (9000,10000]. (i) (ii) (v) Construct a box plot for the annual maximum flow. Are there any suspected and serious outliers? Note: Suspected outliers are data which lie in the range of 1.5- 3.0 IQR below the first quartile (Q1) or in the range of 1.5-3.0 IQR above the third quartile (Q3); while serious outliers are data which lie more than 3 IQR below Q1 or above Q3.
