Suppose the mean weight of King Penguins found in an
Antarctic colony last year was 15.4 kg. In a sample of
35 penguins same time this year in the same colony,
the mean penguin weight is 14.6 kg. Assume the sample
standard deviation is 2.5 kg. At a significance level of
0.05, can we reject the null hypothesis that the mean
penguin weight does not differ from last year?
