QUESTION:
From the Data Bank choose a variable, find the mean, and construct the 95 and 99% confidence intervals of the population mean. Use a sample of at least 30 subjects. Find the mean of the population, and determine whether it falls within the confidence interval.
ANSWER:Solution:
Step 1 of 3:
It is given that from the Data Bank, we need to choose a random variable and then we need to obtain the 95% and 99% confidence interval for the population mean.
Then we need to select a sample of 30 observations from the population and then we need to check whether the mean of the sample falls within the obtained confidence intervals,
