12.72 Changing the response variable. Refer to Exercise 12.65 (page 647), where we compared six types of scaffold material to repair wounds. The data are given as percents ranging from 5 to 75.

a. Convert these percents into their decimal form by dividing by 100. Calculate the transformed means, standard deviations, and standard errors and summarize them, along with the sample sizes, in a table.

b. Explain how you could have calculated the table entries directly from the table you gave in part

(a) of Exercise 12.65.

c. Analyze the decimal forms of the percents using analysis of variance. Compare the test statistic, degrees of freedom, P-value, and conclusion you obtain here with the corresponding values that you found in Exercise 12.65.
