... The only difficulty here is that the constant t/2, appearing on the right-hand side not only depends on , but also on the value of n, through . As a result, we cannot solve for n as cleanly as was possible in the large sample case where the probability factor, z/2, did not depend on n. The reco ...

... interval was found to be $3525 < µ < $4425. This interval is interpreted to mean that (a) if the study were to be repeated many times, there is a 95% probability that the true average summer earnings is not $4500 as the government claims. (b) because our specific confidence interval does not contain ...
