Question

Which of the following Excel functions is used to calculate the exact left-tail probability for a  distribution?
A) CHISQ.DIST(x, Deg_freedom, Cumulative) 
B) CHISQ.DIST(x, n−2) 
C) CHISQ.DIST(x, n/2) 
D) CHISQ.DIST(x/2, Deg_freedom, Cumulative)

Quizplus · Accepted Answer

The CHISQ.DIST function with the "Cumulative" argument set to TRUE is used to calculate the left-tail probability for a chi-square distribution. The "x" argument represents the chi-square value, and the "Deg_freedom" argument represents the degrees of freedom for the distribution. Therefore, option A is the correct choice as it includes all the required arguments.
