TABLE 12-15
Two new different models of compact SUVs have just arrived at the market.You are interested in comparing the gas mileage performance of both models to see if they are the same.A partial computer output for twelve compact SUVs of model 1 and thirteen of model 2 is given below: You are told that the gas mileage population distributions for both models are not normally distributed.
-The Journal of Business Venturing reported on the activities of entrepreneurs during the organization creation process.As part of a designed study,a total of 71 entrepreneurs were interviewed and divided into 3 groups: those that were successful in founding a new firm (n₁= 34) ,those still actively trying to establish a firm (n₂= 21) ,and those who tried to start a new firm but eventually gave up (n₃= 16) .The total number of activities undertaken (e.g.,developed a business plan,sought funding,looked for facilities) by each group over a specified time period during organization creation was measured.The objective is to compare the mean number of activities of the 3 groups of entrepreneurs.Because of concerns over necessary assumption of the parametric analysis,it was decided to use a nonparametric analysis.Identify the nonparametric method that would be used to analyze the data.

The Kruskal-Wallis Rank Test is a non-parametric test used to compare three or more independent groups. It is suitable for situations where the assumptions of normal distribution and equal variances are not met. In this case, the study involves comparing the mean number of activities of three different groups of entrepreneurs, and the sample size for each group is not mentioned. Therefore, the Kruskal-Wallis Rank Test would be the appropriate non-parametric method to use.
