Two samples of a low hardness steel were tested using a Rockwell C hardness tester and the Rockwell B scale at the same lab on the same day . The difference between the average hardness of the two samples was 0.5 Rockwell C. Do you think there is a significant difference in the hardness? Justify your answer. Hint: Use the specification!!

Explain why the same individual can be told they have different ancestry composition when the same data is analysed by different ‘studies’. What other factors do you think might affect the outcome of such tests (4 marks, 4-6 sentences max)? Note: this is not asking about the same data analysed with different stringency values. What are some of the genetic techniques that are currently used to identify ancestry?
