11. The following table shows summary data on mercury concentration in salmons (in ppm) from two different areas of the Pacific Ocean. = Area 1: m = 15, x = 0.0860, sı = 0.0032 Area 2: n= 15, į=0.0884, sı = 0.0028 a. Do the data suggest that the mercury concentration is higher in salmons from Area 2? Assume equal variance and use a = 0.05. Give the 5 steps used in the 5 step method. b. Suppose actual data from this experiment is given below (note, different means and standard deviations) Use R to run the test performed in part (a). The coded needed is in the class notes. Are the results the same as in part a? Area 1 0.086 0.068 0.064 0.103 0.093 0.119 0.115 0.044 0.083 0.072 0.112 0.069 0.098 0.070 0.113 Area 2 0.136 0.044 0.112 0.099 0.062 0.106 0.106 0.076 0.105 0.106 0.110 0.075 0.117 0.094 0.103
