Question

Hilton Marshall · Accepted Answer

There is a significant difference between the performance of boys and girls in the mathematics test. [For the second part of the question regarding coffee consumption after the excise duty increase, the answer would similarly involve statistical analysis, such as a chi-square test, to determine if there's a significant decrease in coffee consumption among the sample of 1200 people after the duty increase. However, since the full answer isn't provided, the simplified version would focus on the conclusion drawn from the analysis.]
