A survey was conducted that asked 976 people how many books they had read in the past year. Results indicated that x= 14.2 books and s= 17.7 books. Construct a 90% confidence interval for the mean number of books people read Interpret the Construct a 90% confidence interval for the mean number of books people read and interpret the result. Select the correct choice below and fill in the answer boxes to complete your choice. (Use ascending order. Round to two decimal places as needed.) O A. There is 90% confidence that the population mean number of books read is between and O B. If repeated samples are taken, 90% of them will have a sample mean between and OC.
