Do the data provide sufficient evidence to indicate

Reference no: EM131028885

Four chemical plants, producing the same products and owned by the same company, discharge effluents into streams in the vicinity of their locations. To monitor the extent of pollution created by the effluents and to determine whether this differs from plant to plant, the company collected random samples of liquid waste, five specimens from each plant. The data are given in the accompanying table.

Plant	Polluting Effluents (lb/gal of waste)
A	1.65	1.72	1.5	1.37	1.6
B	1.7	1.85	1.46	2.05	1.8
C	1.4	1.75	1.38	1.65	1.55
D	2.1	1.95	1.65	1.88	2

a. Do the data provide sufficient evidence to indicate a difference in the mean weight of effluents per gallon in the effluents discharged from the four plants? Test using α = .05.

b. Applet Exercise Find the p-value associated with the test in part (a) using the applet F-Ratio Probabilities and Quantiles.
