here's his draft
few errors though
graph one i tink is x<4
and probability is 1-0.68=0.32
and last question he didnt factor in m=1 so rnage is 20

Yep - they are the old mistakes in terry lee's answers that i see. Hopefully he will correct them soon.

So that's Q3(b)(ii) should be x < 4 not x < 2.
Q4(a)(iii) should be 0.32 not 0.68
Q7(b)(iv) should be 19.51 <= x <= 20 so range is 0.49 or 0.5 (if rounded to 1dp)
