Three subspecies of giraffes were examined for differences in the expression level of the gene MFG in a hypothetical study. The data are summarized below. The giraffes were a random sample of the population and the expression of MFG is normally distributed.

Giraffe subspecies Mean gene expression level relative to control gene sd n
Giraffa camelopardalis antiquorum 2.24 0.932 12
Giraffa camelopardalis camelopardalis 2.19 0.643 14
Giraffa camelopardalis peralta 2.13 0.558 11

a) Using the information provided in the summary table, complete the ANOVA table below.

SS

df

MS

F

Group

Error

b) What is the critical value of F, assuming alpha=0.05?

c) Is the P-value “significant” at alpha=0.05? Write "yes" or "no".

Researchers tested the strength of three brands of trash bags. One pound weights were placed into a bag, one at a time, until the bag broke. The completed ANOVA table is below. The F-test revealed significant evidence that not all bags have equal strength. The following indicates the average amount of weight placed in each bag brand before it broke. Perform the LSD method to determine which bags are significantly different. Use alpha 0.05. Hefty = 34.0 pounds Glad =...
