E-Text Assignment 2 15.17 Employees of Axolotl Corporation were sampled at random from pay records and asked to complete an anonymous job satisfaction survey, yielding the tabulation shown. Research question: At α = .05, is job satisfaction independent of pay category? Employee Pay Type Satisfied Neutral Dissatisfied Total Salaried 20 13 2 35 Hourly 135 127 58 320 Total 155 140 60 355 The first thing to do is to find the null hypothesis and alternative hypothesis.

Unformatted text preview: The raw data was found by using Excel and entering the data into the formulas there. The data is as follows: Critical Value: CHINV(.05,2) = 5.991 Test Statistic = 4.54 P-value = .1032 This data shows that the critical value is greater than the test static. 4.54 < 5.991. All expected frequencies exceed the 5, and the P-value shows that the difference would increase by chance of 10.3% if pay type and satisfaction were independent of each other. This is not enough evidence to reject the null hypothesis that job satisfaction and pay categories are independent of each other. E-Text Assignment 3 References Doane, D. & Seward, L. (2007).
