Question 1081576: a survey was conducted that asked 1003 people how many books they had read in the past year. Results indicated that x= 14.8 Books & S= 16.6 books. construct a 95% confidence interval for the mean number of books read. Interpret the interval.
construct a 95% confidence interval for the mean number of books people read and interpret the results. Select the correct choice below and fill in the answer boxes to complete your choice.
a) if repeater samples are taken, 95% of them will have a sample mean between [ ] and [ ].
b) there is a 95% chance that the true me number of books read is between [ ] and [ ].
c) there is 95% confidence that the population mean number of books read is between [ ] and [ ]. Answer by stanbon(75887) (Show Source):

-------
sample mean:: x-bar = 14.8
margin of error:: E = 1.96*16.6/sqrt(1003) = 1.027
-------
95% CI:: 14.8-1.027 < u < 14.8+1.027
----
Ans:: c) there is 95% confidence that the population mean number of books read is between [13.773] and [15.827].
