Refer to Fortune (Oct. 25,1999) magazine's study of the 50 most powerful women in America. Exercise 2.36

(p. 59). The data table, reproduced below, gives the aye

(in years) and title of each of these 50 women. Suppose you want to compare the average ages of powerful women in three groups based on their position (title)

within the firm: Group 1 (CEO, CFO, CIO, or COO);

Group 2 (Chairman, President, or Director); and Group 3 (Vice President,Vice Chairman, or General Manager).

A MINITAB analysis of variance is conducted on the data, with the results shown in the printouts on p. 413-415. Fully interpret the results. Give the null and altcrnative hypotheses tested. Also, determine whether the ANOVA assumptions are reasonably satisfied.
