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?
Let t_{0.025;34}=2.032
(i) t_{0}=-1.8931 reject H_{0}
(ii) t_{0}=-1.8931 fail to reject Ho
(iii) t_{0}=1.8931. reject H_{0}
(iv) t_{0}=1.8931 fail to reject H_{0}
