Strategies
Compare the word lengths and sentence lengths of two novels one modern and one historical novel. The novels must be as different as possible so that the statistical theories will work.
Stats depend on an author’s style of writing and not the publishers efficient for example an author wont change the way he writes like words and sentence lengths will always be similar, but a publisher will change things like number of pages in a book or number of lines on a page.
Therefore I will take the random samples of the word lengths and sentence lengths.
Statistical theories depend on the samples being random I am going to find the mean an standard deviations of the samples and using this information make an unbiased estimation of the population μ and σ then I will find the confidence intervals for the population μ and compare them.
Convidence intervals are an interval estimate of an unknown population parameters constructed so that it has a given probability of including the parameters.
Consider a population with unknown θ
If we can find an interval (a , b) such that P(a< θ <b) = 0.95, we say that (a , b) is a 95% confidence interval for θ.
Objectives
Before each calculation write first what it is that you are going to do and why.
