In order to test the hypothesis that the girls in her class are taller than the boys, Mary measures the heights of the first five girls and five boys listed on the class register. She finds the mean height of the girls is 162cm and the mean height of the boys is 158cm. Is she justified in believing her hypothesis has been confirmed? Justify your answer fully. How would you have tested the hypothesis?

I've done why she can't be justified in believing her hypothesis, but I've not much of an idea on How I would test the hypothesis? I know it should be a random sample but I'm not sure where to go from there
What year group? If A level then which module?

There is no level, it's on a interview test.

The only thing I can think of is do a random sample which is representative and then find the mean and compare.

Or based on the assumption that the class is small (most classes are) just measure everyone and find the mean.
I think they are more interested in your ideasin the interview rather than mine ...
