<p>The (-3,3) might be the best answer choice, but still… it was a sly question :(</p>

162

<p>Wow, ahage, if that WAS the wording, then that was a dick question…</p>

<p>D:</p>

163

<p>anyone want to send something to collegeboad about that question? = D</p>

164

<p>Seriously. I am so mad over that question! Who wants to dispute it with me</p>

165

<p>lets just send hatemail to them LOL</p>

166

<p>I still don’t understand how the frequencies was 4… anyone care to explain?</p>

167

<p>I will, I just don’t know where to submit a dispute. .</p>

168

<p>Even though I got it wrong, I think (-3,3) is the correct answer. About the frequencies, say they gave you this table (I don’t remember the values)
Values Frequecies
1 0
2 3
3 x
4 2</p>

<p>And it said that the mean of the set was equal to one of the values, the mean would equal…
(0<em>1 + 2</em>3 + 3<em>x + 4</em>2)/(0 + 3 + x + 2)</p>

169

<p>Any number > 2 squared is greater than 4. Am I missing something? O_O</p>

170

<p>Haha olleger I’m sending it to collegeboard. If enough people dispute it, will they throw it out?
Has that ever happened?</p>

171

<p>which Q no. was the question??</p>

172

<p>the table was
1
2
3
x
1
… and 4 would not work.</p>

<p>@ilikebannas, someone is doing that for the PSAT so its worth a try.</p>

173

<p>wait… the X was next to the 4, not the 3.</p>

<p>and @ ahage, there are directions somewhere on the Collegeboard site underneath “after the test.”
I’ll post when I find out the specific instructions.</p>

174

<p>@olleger</p>

<p>I put 3. My reasoning is that they said the mean of the frequencies was one of the values and all of the values were integers. There were five frequencies, so the sum of the frequencies had to be a multiple of five. The sum of the given frequencies was 7, so in order to make it a multiple of 10, the missing one would have to be 3.</p>

175

<p>the question under dispute, what number was it? 10-20, 30-40 etc???</p>

176

<p>well X was one of the frequencies</p>

177

<p>@ahage exactly my thinking.</p>

178

<p>@xAAAx</p>

<p>I think it was question 48 or 49.</p>

179

<p>I think it was a question in the 40s</p>

180

<p>Doesn’t it make more sense for them to ask for the mean of the data instead of the frequencies?
I don’t remember the wording of the question though.</p>
