**Section 9.2.30: Constructing a Confidence Interval**A survey was conducted with 1014 participants to determine how many books they had read in the past year. The survey results yielded an average ($ \bar{x} $) of 14.4 books with a standard deviation (s) of 16.6 books. Your task is to construct a 90% confidence interval for the mean number of books read by the population, and interpret this interval.### Instructions- Click the icon to view the table of critical t-values.### TaskConstruct a 90% confidence interval for the mean number of books read and interpret the result. Select the correct choice below and complete the answer boxes provided.*(Use ascending order and round to two decimal places as necessary.)***Options:**- **A.** If repeated samples are taken, 90% of them will have a sample mean between [____] and [____].- **B.** There is a 90% probability that the true mean number of books read is between **15.53** and **13.70**.- **C.** There is 90% confidence that the population mean number of books read is between [____] and [____].**Note**: The correct answer is option **B**, and the values in the boxes are **15.53** and **13.70**, which are incorrectly not in ascending order. Please correct this when inputting the values.--- This section helps to understand the concept and application of confidence intervals in statistics, allowing one to infer population parameters from sample statistics.

It is given that sample mean is 14.4 and the standard deviation is 16.6.
