Question: question 4 and 5 to find that pooled standard deviation. Chemical Treatment SEM SD Variance 2-Phenylethanol Control 57 180 32490 2-Phenylethanol Exposed 31 98 9604

question 4 and 5

to find that pooled standard deviation. Chemical Treatment SEM SD Variance 2-Phenylethanol Control 57 180 32490 2-Phenylethanol Exposed 31 98 9604 a-pinene Control 29 91 8281 a-pinene Exposed 20 45 2000 4. Next, let's calculate the pooled standard deviation for both comparisons to determine a measure of shared variation. Emily a. 2-phenylethanol pooled standard deviation: b. a-pinene pooled standard deviation: 5 . Finally, calculate cohen's D to determine the effect size for diesel's effect on the chemical's presence. Emily a 2-phenylethanol effect size: b. a-pinene effect size
