Chapter 9.3, Problem 4E
The effect of curing pressure on bond strength was tested for four different adhesives. There were three levels of curing pressure. Five replications were performed for each combination of curing pressure and adhesive. With adhesive as the row factor and curing pressure as the column factor, the sums of squares were: SSA = 155.7, SSB = 287.9, SSAB = 156.7, and SST = 997.3.
- a. Construct an ANOVA table. You may give
ranges for the P-values. - b. Is the additive model plausible? Explain.
- c. Is it plausible that the main effects of curing pressure are all equal to 0? Provide the value of the test statistic and the P-value.
- d. Is it plausible that the main effects of adhesive are all equal to 0? Provide the value of the test statistic and the P-value.

To assess the effect of piston ring type and oil type on piston ring wear, three types of piston ring and four types of oil were studied. Three replications of an experiment, in which the number of milligrams of material lost from the ring in four hours of running was measured, were carried out for each of the 12 combinations of oil type and piston ring type. With oil type as the row effect and piston ring type as the column effect, the following sums of squares were observed: SSA = 1.0926, SSB = 0.9340, SSAB = 0.2485, SSE = 1.7034. a) How many degrees of freedom are there for the effect of oil type? b) How many degrees of freedom are there for the effect of piston ring type? c) How many degrees of freedom are there for interactions? d) How many degrees of freedom are there for error? e) Construct an ANOVA table. You may give ranges for the P-values. f) Is the additive model plausible? Provide the value of the test statistic and the P-value. g) Is it plausible that the main effects of…
Globally, 35% of all ridged brittleshell tortoises have spots on their shells. A herpetologist in Citition collects a sample of 38 ridged brittlesell tortoises and finds that 16 of them have spots on their shells. The herpetologist would like to test the claim that the proportion of ridged brittleshell tortoises in Cititon with spots on their shells is greater than 35%.
The herpetologist ends up rejecting the null hypothesis. If the actual proportion of ridged brittleshell tortoises in Cititon with spots on their shells is 41%, then what type of error, if any, has occurred?
In the problem above, what is the test statistic?
Given the number of rows = 5, dfWithin = 24, and alpha is set at .05, what is q when calculating Tukey's HSD for a row effect?

- To determine the effectiveness of an oil additive, a testing firm purchased two cars of the same make, year, and model, and drove each a distance of 30,000 miles using the same kind of gasoline, the same kind of oil, the same driver, under the same road conditions. The oil in one engine included the additive, whereas the oil in the other engine did not. At the end of the test, the engines of both cars were dismantled, and it was found that the engine that contained the additive had less wear. The testing firm concluded that the oil additive caused the reduced wear.arrow_forwardBelow is the incomplete summary table for an ANOVA. Source SS df MS F Factor A 420 ? ? ? Error ? 21 ?

Manipulations of ½ meter square plots (20 plots per manipulation) included removing all cordgrass (cordgrass removal), removing all pickleweed (pickleweed removal), or mixed (the control - nothing removed, thus mixed plots included a mixture of natural pickleweed and cordgrass). Boxplots of ammonium concentrations in each of the three manipulation treatments. Letters indicate differences among means as determined by a Tukey posthoc test following ANOVA.
