Tests оf the flаmmаbility оf children's sleepweаr were cоnducted independently by three different labs. Results are shown in the table below. Perform an ANOVA and answer the following questions.What is the average flammability rating reported by Lab#2? [avglab2] (round to 2 decimals)What is the variance in flammability rating for Lab#1? [varlab1] (round to 2 decimals)What is the p-value for this ANOVA? [pval] (note: round to 3 decimals)At an alpha of 0.05, is there a significant difference in the mean of flammability between the labs? [sig] (enter yes or no) Lab#1 Lab#2 Lab#3 2.5 4.3 3.0 3.0 3.4 3.2 2.9 4.1 2.4 3.0 3.4 3.3 2.8 3.7 2.2 2.6 4.1 2.6 2.6 3.5 1.9 2.6 3.9 3.7 3.4 3.3
The fоllоwing dаtа shоws the results from trying to teаch various tricks/commands (i.e., Sit, Shake, Roll Over) to young dogs (i.e., "Puppy") and older dogs (i.e., "Old Dog"). The numbers represent how much training it takes (i.e., how many times the command must be repeated) before the dog is able to do the trick on command. Perform the appropriate ANOVA and answer the following questions.Does the analysis consider a possible interaction between the factors (i.e., the age of the dog and the type of trick) that needs to be examined? [inter] (enter yes or no)If so, what is the p-value associated with the interaction? [pint] (round to 3 decimals)Is the interaction statistically significant at alpha=0.05? [intsig] (enter yes or no)What is the is the p-value for the difference between puppies and old dogs in the average training required to learn a trick? [pcorn] (round to 3 decimals)At an alpha of 0.05, can we say the difference between puppies and older dogs is meaningful and significant? [sigage] (enter yes, no, or na if the question cannot be answered)What is the p-value for the difference between the type of tricks? [pplot] (round to 3 decimals)At an alpha of 0.05, can we say the difference in the average required training between the various tricks is meaningful and significant?
