I need help checking if this is a normal model. I made a box plot but it doesn't look normal to me. Also how do i do a randomization test?

T 82. Swimming heats London In Exercise 81, we looked at the times in two different heats for the 400-m women's run from the 2012 Olympics. Unlike track events, swimming heats are not determined at random. Instead, swimmers are seeded so that better swimmers are placed in later heats. Here are the times (in seconds) for the women's 400-m freestyle from heats 2 and 5. Do these results suggest that the mean times of seeded heats are not equal? Explain. Include a discussion of assumptions and conditions for your analysis. (*Use a randomization test to test the difference. Do your con- clusions change?)
