Question

Chi-Square Test for Independence  

Using Chi-Square, we are looking to see if there is a significant difference between what we would expect results to be, and what the actual results were.  That is, expected vs. observed.   Use alpha = .05

Listed below are data from a survey conducted recently where Males and Females responded to their happiness with their supervisor (this is fictitious data).  

Response	Male	Female	Total
Not at all	23	25	48
Somewhat	13	22	35
Very	26	16	42
Total	62	63	125

What is your null hypothesis?

What is your alternative hypothesis?

What is the Chi-Square value?

Is there significance evidence that a difference exists between the actual males and female responses in this sample and the expected male/female responses in the population?  YES OR NO

Answer 1

H0: there significance no evidence that a difference exists between the actual males and female responses in this sample and the expected male/female responses in the population

H1: there significance evidence that a difference exists between the actual males and female responses in this sample and the expected male/female responses in the population

Given the los be alpha = 5%
