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).

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
I need help. Thanks.
