Answer: It is 95% certain that it contains the true mean of the population.
Step-by-step explanation:
We know that a 95% confidence interval gives an interval such that you can be 95% sure that it contains the true mean of the population.
Given : The pages per book in a library are normally distributed with an unknown population mean.
A random sample of books is taken and results in a 95% confidence interval of (237,293) pages.
Then, the correct interpretation of the 95% confidence interval is that it is 95% certain that it contains the true mean of the population.
