Indicate clearly the methods you use, because you will be graded on the correctness of your methods, as well as on the accuracy of your results and explanation. for part a, briefly describe the scatterplot you construct on your calculator (include labels). animal-waste lagoons and spray fields near aquatic environments may significantly degrade water quality and endanger health. the national atmosphere deposition program has monitored the atmosphere ammonia at swine farms since 1978. the data on the swine population size (in thousands) and atmospheric ammonia (in parts per million) for one decade are given below. year 1988 1989 1990 1991 1992 1993 1994 1995 1996 199 swine population 0.38 0.50 0.60 0.75 0.95 1.20 1.40 1.65 1.80 1.85 atmospheric ammonia 0.13 0.21 0.29 0.22 0.19 0.26 0.36 0.37 0.33 0.38 a) construct a scatterplot for this data. (find out from your instructor on how to submit your scatterplot). b) the value for the correlation coefficient for this data is 0.85. interpret this value. c) based on the scatterplot in part (a) and the value of the correlation coefficient in part (b), does it appear that the amount of atmospheric ammonia is linearly related to the swine population size? explain. d) what percent of the variability in atmospheric ammonia can be explained by swine population size?
