    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 ☺️

    65803111[/url]]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
