When to Use What: For each example below you would start to construct a confidence interval by identifying which distribution should be used to find the margin of error. It is possible that you won't be able to use either distribution.
(a) a confidence interval for a population proportion where n = 45 and there are 27 successes in your sample leading to a sample proportion of 0.600
t-distribution
z-distribution
neither distribution
Homework Answers
solution
given that
n = 45
x=27
sample proportion of 0.600
random sample is larger than 30 than use z - distribution
correct answer is =z-distribution
