Question

This applet illustrates 95% confidence intervals for samples from a normal distribution with known variance. (a) When taking 100 samples of size 30 or greater from a population, exactly 95 of them will create a confidence interval that contains the true population mean. True False (b) Which statement is the correct interpretation of the confidence interval in this illustration?

Answer 1

Answer:

Step-by-step explanation:

When taking 100 samples of size 30 or greater from a population, exactly 95 of them will create a confidence interval that contains the true population mean. True or false?

This statement is false, or better still, ambiguous. 100 samples of size 30 (or greater) each, means 300 total and it can't be just 95 of them that will contain the true population mean.
