A data set of 27 male African elephants shows that their weights are normally distributed, and have an average weight of 111 kg, with a 95% confidence interval of (104, 119). I was asked to find an appropriate hypothesis test for this data set, and do the calculations and interpret the data, but if I feel that there are no natural hypothesis testing to carry out, then I should state why not. I personally feel there is no natural hypothesis...
