Question 8 on core cannot be D because the x-axis doesn't begin from 0. Therefore the y-intercept cannot be 17.4, t'was a tricky question.

Y-intercept is where x = 0

I realised my mistake :(

Thanks

Shouldn't Q13 be E as the data value for day 21 is higher than the data value of day 1, so therefore it should have irregular fluctuations with an increasing trend.

yep - i plused 3points before the 4th day (including the 4th day) and 3 points after that... and then divided by 7 = approx 32....... what did I do wrong?

That's MEAN smoothing, not MEDIAN

I applied the same reasoning as you and got E as well.

Overall there is no increasing trend in the data. There would have been an increasing trend had the peaks become higher values each time as well as the minimum values increasing over time, however they stayed relatively level through the data indicating no increasing trend.
