Question

Find the critical values chi Subscript Upper R Superscript 2 and Chi Subscript Upper L Superscript 2 for the given confidence level c and sample size n.

c= 0.80, n= 30

X upper 2 lower R =___ (round to three decimal places as needed)

X upper 2 lower L =___(round to three decimal places as needed)

Definition Definition Number of subjects or observations included in a study. A large sample size typically provides more reliable results and better representation of the population. As sample size and width of confidence interval are inversely related, if the sample size is increased, the width of the confidence interval decreases.
