One concern about the depletion of the ozone layer is that the increase in UV light will decrease crop yields. An experiment was conducted in a green house where soybean plants were exposed to varying levels of UV levels - measured in Dobson units. At the end of the experiment the yield (kg) was measured. The sample size was 500. A regression analysis was performed with the following results: Here is some output: Variable Constant dose Coefficient 3.96 SE of Coeff 0.054 T P 4.096 3.30 0.011 4.31 0.0002 0.0008 An approximate 95% confidence interval for the slope is O a. 3.3 ± 0.011 O b.3.3±0.021 O c. 3.3±0.054 O d. 3.3±0.046 Oe. 3.3±0.108 D
