(f) Another river is a smaller but very important source of water flowing out of the park from a different drainage. Ten recent years of annual water flow data are shown below (units 10^8 cubic meters).
3.83 3.81 4.01 4.84 5.81 5.50 4.31 5.81 4.31 4.57
Although smaller, is the new river more reliable? Use the coefficient of variation to make an estimate. (Round your answers to two decimal place.)
original river's coefficient of variation ____
smaller river's coefficient of variation ____
What do you conclude?
A. The smaller river is more consistent.
B. Neither river is more consistent.
C. The original river is more consistent.
(g) Based on the data, would it be safe to allocate at least 26 units of the orginal river water each year for agricultural and domestic use? Why or why not?
A. No, the median is less than 26 which means more than half the river flows are below 26.
B. No, Q3 is less than 26 which means more than three quarters of the river flows are below 26.
C. No, since 26 is an upper outlier it will be very rare to have a flow at or above 26.
D. Yes, since 26 is an lower outlier it will be very rare to have a flow below 26.
E. Yes, Q1 is greater than 26 which means over three quarters of the river flows are at or above 26.
