Question

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

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
