Ho: H1 - H2 = 0 Ha: H1 - H2 > 0 To address the hypotheses above, data were collected from two small independent samples. Sample statistics are presented in the following table: Summary Statistics Group N Mean Standard Deviation Group 1 14 10.054 3.485 Group 2 13 9.815 3.279 The data collected from Group 1 were skewed to the right. The data collected from Group 2 were approximately normal. The shape of the population distributions is unknown. It is appropriate to use the t distribution to analyze these data? Yes, the t distribution may be used No, the t distribution should not be used
