The table above lists the lengths, to the nearest inch,

of a random sample of 21 brown bullhead fish. The

outlier measurement of 24 inches is an error. Of the

mean, median, and range of the values listed, which

will change the most if the 24 -inch measurement is

removed from the data?

$$\begin{array}{l}{\text { A) Mean }} \\ {\text { B) Median }} \\ {\text { C) Range }} \\ {\text { D) They will all change by the same amount. }}\end{array}$$

so again, it says the function H is defined by age of tea is he could eighty plus B where A and B are Constance. Well, that looks like a form of Isaac. What's a next class B, where M is our slope? So they've just replaced with A and X with tea. That's the same thing. So we know that em and they are the same thing. Well, that means that M and A are both slopes, which are rates. So we're looking for something that talks about, like rats either a slope or a rate or something like that. So let's look at it So A says the predictive number of centimeters to sun flower goes each day during the period. Well, so they're talking about growth per day, so that sounds like a rate rose per day. So that's probably good answer. But let's go in and go through the other ones, he says. The heightened centimeters of the something at the very beginning. Well, that zero, and that's the white intercepts. So we know that that one is actually that be value, so that's not correct, See, says predicted, heightened centimeters at some flower at the end of period. Well, that's just this value. And that's just a value of age of eighty four. Because that's at the very advanced. Let's not sea bass is the predicted total increase in the height of the sunflower and centimeters during the period. Well, the total predicted height increase is just the difference between the final value and the initial value. So that's also not a rate we don't want to choose that, so a is going to be our correct answer.
