Question
in this question I am asking, only answer exercise 6-76 preferably.

Transcribed Image Text:6-40. An important quality characteristic of water is the con-
centration of suspended solid material. Following are 60 meas-
urements on suspended solids from a certain lake. Construct
a stem-and-leaf diagram for these data and comment on any
important features that you notice. Compute the sample mean,
the sample standard deviation, and the sample median. What is
the 90th percentile of concentration?
42.4 65.7 29.8 58.7 52.1 55.8 57.0 68.7 67.3 67.3
54.3 54.0 73.1 81.3 59.9 56.9 62.2 69.9 66.9 59.0
56.3 43.3 57.4 45.3 80.1 49.7 42.8 42.4 59.6 65.8
61.4 64.0 64.2 72.6 72.5 46.1 53.1 56.1 67.2 70.7
42.6 77.4 54.7 57.1 77.3 39.3 76.4 59.3 51.1 73.8
61.4 73.1 77.3 48.5 89.8 50.7 52.0 59.6 66.1 31.6

Transcribed Image Text:6-76. + Reconsider the water quality data in Exercise 6-40.
Construct a box plot of the concentrations and write an inter-
pretation of the plot. How does the box plot compare in inter-
pretive value to the original stem-and-leaf diagram?
