A survey was conducted that asked 1022 people how many books they had read in the past year. Results indicated that \( \bar{x}=15.2 \) books and \( s=16.4 \) books. Construct a \( 98 \% \) confidence interval for the mean number of books people read. Interpret the interval. Construct a \( 98 \% \) 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.) A. There is \( 98 \% \) confidence that the population mean number of books read is between B. If repeated samples are taken, \( 98 \% \) of them will have a sample mean between \( \square \) and C. There is a \( 98 \% \) probability that the true mean number of books read is between

Homework Determine the point estimate of the population proportion, the margin of error for the following confidence interval, and the number of individuals in the sample with the specified characteristic, \( x \), for the sample size provided. Lower bound \( =0.529 \), upper bound \( =0.831, n=1500 \) (Round to the nearest thousandth as needed.) The margin of error is \( \square \). (Round to the nearest thousandth as needed.)

Determine the point estimate of the population mean and margin of error for the confidence interval. Lower bound is 21 , upper bound is 29 . The point estimate of the population mean is 1

The grades on the second statistics test for Mrs. Sweeney's class are in the following list. Find the frequency distribution for the grades, \[ \text { D, F, B, D, A, F, F, B, F, F, B, C, C, C, B, F, C, A, B, B, F } \]

Determine whether the following statement is true or false. To construct a confidence interval about the mean, the population from which the sample is drawn must be approximately normal. This statement is

The grades on the second statistics test for Mrs. Sweeney's class are in the following list. Find the frequency distribution for the grades. \[ \text { D, F, B, D, A, F, F, B, F, F, B, C, C, C, B, F, C, A, B B, B F } \] Answer
