13.1.5 chi squared​-value

For a \(\chi^2\)-curve with 22 degrees of​ freedom, find the chi squared ​-value that has area 0.05 to its right.


\(\chi_\alpha^2\) has \(\alpha\) is the area to the right under \(\chi\) curve

We can get \(\chi^2\) value by using the table or we can run qchisq()

qchisq() takes in the area to the left and degree of freedom

qchisq(.95,22)
## [1] 33.92444

Round to three decimal places

round(qchisq(.95,22),3)
## [1] 33.924


Hope that helps!
