I thought it was okay, better than the pure paper which parts of it I found very difficult. The question with the large data set I fully chose random numbers I had no clue, but everything else I managed to do I think, but I'm sure I made many stupid mistakes or used the wrong methods etc.

u got the graph for frequency density on y axis and height on x axis, So you know the area underneath is the frequency. As the limits are 8 and zero u do definite integration between those two points to get k.

That sounds right but also wouldn't doing integration with limits and stuff fall under pure maths not applied?
