I got 3 for 10 but I'm not sure whether the middle one is a cusp or not, I'll do some investigating when i get home.Anyone know what the answers were for Q8 and Q10?
You needed to find the average temperature (which was 0.565 or something below the median from the box-and-whisker plot) and the average number of chirps per recording. Using these two values you get a point (x, y) which the least-squares regression line passed through. Subbing in that point you can solve for b, and that gave you a complete equation with which you could sub in x=19.How did you guys get the cricket question?
same... I felt like the paper in itself was pretty easy tbh especially section 1. I just wish I actually fking studied bc I know I couldve done it well, I just didn’t know how to apply what I learnt to test questions oh wellomg that would have been okay if i studied but here i am with probably sub 10 percent
60000(1.005)^94 - 800(1+1.005+1.005^2.....+1.005^93)Does anyone remember the investment question? and what did you guys get for the 94th withdrawal?
honestly, it was like. the scientist record the cricket sounds every 15 minutes and the box plot ranged from like (not sure) 15 to 24 or something, cant remember sorry. There were like 468 cricks and they wanted us to find the expected value of the cricks at 19 degrees cel.does anyone remember roughly what details they gave in the cricket question extract and what the question actually was? It’s killing me not knowing, I wanna try it again lmfao
