Nope, sorry but the mean did decrease! It's only one or two marks though

They specifically asked for how it changes the ESTIMATE for the mean, no ambiguity

We'll have to agree to disagree ☺️

Think I managed the 6 UMS I need for an A* assuming I get 90 in C3 and C4 so I'm happy

[QUOTE=googleit;65803111]We're dealing with classes mate, so the mean contributes to the 3-3.5 class. Think about it very carefully. The mean decreases slightly.

The reason why we need to multiple by the class midpoint is because we don't know the exact values so we find the average. That's why it asks to "estimate" the mean. However we were given an exact value of 3.43 so we just use that. Doing what you say would just lower the accuracy ever more for no reason .

So it stays the same

did you find 1/x first then mutliplied that by the probability, adding each one?
