Lesson 8 Q8

Find the critical values X²_R and X²_L for an 80% confidence when the sample size is 29.

Find the critical values XRand X, for an 80% confidence when the sample size is 29.
X2R = 39.251
X²L = 18.939
X2R = 35.563
X²L = 12.443
X2R = 37.916
x2
X²L = 18.939
x2 R
= 39.087
X²L = 19.768

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.
