An entomologist conducts an experiment to study the side e ects of a new pesticide. She simultaneously exposes 100 mice to the pesticide. The amount of pesticide in their bladder (ppm) was recorded 30 days after the exposure. The 100 values are displayed in the following normal reference distribution plot. The Shapiro-Wilk test yielded SW = .793 and plotted line is bQ(u) = 19:99+2:82QZ(u). Select the distribution which best describes the cdf, F, for the amount of pesticide in the mice's bladder. 2.5 2.0 1.5 1.0 0.5 0.0 0.5 1.0 1.5 2.0 2.5 8 10 12 14 16 18 20 22 24 26 28 30 32 Normal Reference Distribution Plot Standard Normal Quantiles, Q(u) Sample Quantiles Y = 19.99 + 2.82 Q(u) SW = .793 A. F() has a N(20,3) distribution B. F() has a shifted t-distribution with df=3 and centered at 20 ppm C. F() has a shifted t-distribution with df=40 and centered at 20 ppm D. F() has an Exponential( = 20) distribution E. None of the above are an appropriate model based on the 100 data values
