A researcher wants to know if the clothes a woman wears is a factor in her GPA. The table below shows data that was collected from a survey. Shorts Dress Jeans Skirt 1.9 3.9 3.9 3.3 2.3 3.4 4 3.7 3.1 3.3 2.5 3.4 3.9 2.3 3.7 2.1 2.4 2.5 3.7 4 3 2.5 3.9 3.1 2.5 2.6 3.8 2.7 2.4 2.5 Assume that all distributions are normal, the four population standard deviations are all the same, and the data was collected independently and randomly. Use a level of significance of a = 0.1. Ho: µi = µ2 = µ3 = M4 H1: At least two of the means differ from each other.
