agree or disagree with Through a virtual library I collected the following ages (in years) of 10 randomly selected books: 5, 12, 8, 25, 3, 15, 10, 7, 20, 30. First, we would need to calculate the mean: Mean Age(x)=105+12+8+25+3+15+10+7+20+30=10/135=13.5 years. Then we would calculate the standard deviation, afterwards the confidence interval. Lastly, once you have the confidence interval, you can estimate the average age of all the books in the library. So, if the interval comes out to be between 10.2 and 16.8 years, you can be 95% sure that the true average age of the library's books falls within that range
