Hi Lauren, can you move this into the sports science project please.

You've left it a bit in the air whether you are testing the student on which type of test to use. A t-test is implied in part (d), so I would either remove that to just say "test statistic" and start the question with a multiple choice asking which type of test is appropriate, or perhaps just state explicitly that the method will be to use a t-test in the statement.

I would split (d) into two parts, one to identify the significance level (also multiple choice) and the second to draw a conclusion from it.

You should split the advice by parts to help the student to easily digest the information.

Fixed bug in correct line plot, caused by reading wrong student answer box (must have had a part added)
