Evaluate the integral ∫ cosht/sinh^2t(1+sinh^2t) by using the
following two different methods: (a) make a substitution to express
the integrand as a rational function and nd its partial fraction
decomposition (b) use properties of hyperbolic functions to
simplify the integrand

A market analyst wants to know if the new website he designed is
showing increased page views per visit. A customer is randomly sent
to one of two different websites, offering the same products, but
with different designs. The accompanying table shows the data from
five randomly chosen customers from each website. Test the null
hypothesis that the mean number of page visits is the same for the
two websites. Assume that the data come from a population that is...
