Question: Three different acoustical systems are proposed for controlling noise intensity in an office. Measurements of noise intensity (decibels) that simulate heavy street traffic are made

Three different acoustical systems are proposed for controlling noise intensity in an office.

Measurements of noise intensity (decibels) that simulate heavy street traffic are made for all three acoustical systems at various locations in the office. Using a 5% level of significance, test whether or not the mean noise intensity for the three systems differs.

System 1 22 28 26 25 23 System 2 31 34 29 36 34 System 3 19 23 22 25 21
