Question
Ariane has geese on her farm. She claims the meah weight of eggs from her black geese is
less than the mean weight of eggs from her white geese.
She recorded the weights of eggs, in grams, from a random selection of geese. The data is
shown in the table.
Weights of eggs from black geese
136
134
142
141
128
126
Weights of eggs from white geese
135
138
141
140
136
134
In order to test her claim, Arriane performs a t-test at a 10% level of significance. It is assumed
that the weights of eggs are normally distributed and the samples have equal variances.
(a) State, in words, the null hypothesis.
(b) Calculate the p-value for this test.
(c) State whether the result of the test supports Arriane's claim. Justify your reasoning.
