Do you happen to have any additional questions similar to mixed exercise 3 Q8d and 9c? My group are struggling with this and the solution bank sets out the linear interpolation using fractions.

For slide 27, should the calculation not be 19.5 + (195/240)x11 instead of 20 + (195/240)x10 as the class width for the 20-30 category is 11?

The Chp3 for S1 doesn't have the supplementary sheets for the box plots... am I looking in the wrong place for them? I can only find a histogram supplementary sheet?

Slide 24 should be a sf of 2.5 not 2.4 & then there are 37.5 people.

Slid 24 there is an error in calculation when doing 60 divided by 24 to get 2.4 when the real answer is 2.5 also the use of scaling is completely wrong
