gcse statistics 27th June, how did you find it Watch

You got 91.6% ?
And also the question about histogram a and the first 21 people , what did you get? I got 110 but i don't think it's right
I got 91.6 too
2. You probably interpreted x^2 as (the total of x)^2 rather than the correct interpretation as (x^2 + x^2 + x^2 + x^2 etc.). I made this mistake at first but then realized where I went wrong after 10 minutes attempting to solve the issue 😆
3. I got 94.9% I think For the normal distribution Q and I rounded it up to 95% and wrote that it could be modelled by normal distribution

I think it was alright, grade boundaries should be between 76-78 I think.
Why between 76-78?
6. What did you get for the seasonal variation one or something, last part? 2300 million? The test was harder than the other ones that's for sure, I messed up quite a bit YET AGAIN! I got 133.3 for the gradient but idk if i did well anymore in any of my exams. My confidence is so low man!

You do seasonal variation for the 3 quarter 1's add them up and divide by 3 and add it on
The seasonal variation was - something and then add it on

weren't the answers like all - numbers since trend line was above actual line?
