"Linear simultaneous equations in two unknowns, that are neither equivalent nor contradictory, have one set of values that will make a pair of equations true at the same time."

first line of the solution should say >2 rather than >x, in order to match the question

Daily mean temperature recorded over a 24 hour period is recorded for all locations.

Ignore final sentence about maximum and mean temperatures.
page 66 question 3 part a)
on the graph, amend the x axis label to "Number of items (n)"
there is a mismatch between the question and the answer
"The equation of the regression line of g on t for the remaining data is g = 44.9 - 0.47t
c) Give an interpretation of the value -0.47 in this regression equation"
page 216 Mixed Exercise 4 question 5 part c)
"If the temperature increases by approximately 1 degree C, the number of pairs of gloves sold each month decreases by 0.47."
The Solutionbank answer for this uses the regression line of t on g as given, but has a totally different answer for part c based on 10 gloves predicting a 1.8 degree drop of temperature.
