Question

Hey Chegg, I could use your help with this question.

These are the Chi-square practice templates that I downloaded from an microsoft excel file

Help me complete 3 chi-square tests (observed, expected, chi square) (1 in each sheet) and indicate whether or not the variables are independent (or related to each other)

Please provide the p-value and the alpha

I would really appreciate if you can please show your work and explain step by step how you completed the 3 chi-square tests (1 in each sheet) and please explain if the variables are independent or not and why. Thanks in advance

Row Labels Male Female Total didn't complete high school 362 398 high school degree 672 750 some college 488 450 college degree 506 484 post-undergraduate degree 147 158 Total

Explanation / Answer

from above given detail: below is the solution ; please follow formulas in the cells

here chi stat X2 =7.453

degree of freedom =(number of rows-1)(number of columns-1) =(5-1)*(2-1)=4

for 4 degree of freedom and chi stat 7.453 ; p value=0.1138

as we do not know alpha we consider it 0.05 default value

for p value is higher then 0.05 level we can not reject null hypothesis and conclude that we do not have sufficent evidence that variables are dependent

please reply for doubt
