Question

Data in the table below summarize results from a replicated, two-factor lab test examining the effects of two different temperatures and two different lighting schemes on algal growth rates. Four treatments were applied, where +1 treatments refer of higher temperature or more light, and -1 treatments refer to lower temperature or less light. Use this information to conduct an ANOVA to examine the effects of temperature, light, and temperature light on the growth rate Light Replicates 114.059 97.079 89.089 47.959 Temperature 88.589 56.949 65.439 40.799 -1 200.979 78.759 172.339 74.439 -1 -1 -1 5. 6. 7. 8. What is the mean square error term associated with light? What is the F-value associated with temperature effects? What is the P-value associated with light effects? Based on a plot of residuals as a function of the fitted values, does the variance appear to satisfy the assumptions of the model?
