Calculating Margin of Error for 95% Confidence Interval in Rent Predictions

AI Thread Summary
To determine the margin of error for a 95% confidence interval in rent predictions, the discussion centers on calculating the appropriate value, with options provided ranging from $57 to $228. The correct answer is identified as $114, derived from the standard error calculation, which typically involves multiplying by a critical value associated with the confidence level. Participants reference a statistical inference for regression test and suggest reviewing specific lecture slides for further clarification on the methodology. The conversation emphasizes the importance of understanding the standard error in relation to confidence intervals. Additional assistance is offered for those needing more guidance on the topic.

To capture the actual Rent amount 95% of the time, predictions from the fitted equation should include a margin of error of about plus or minus ______ (round to the nearest ten dollars).
$128
$114 (answer)
$57
$228
Here's a pic of the table. How did they get the answer? http://picturetrail.com/sfx/album/view/24285022
I know k2= 95%. I know you do 2 * (standard error) but I don't see that on the table.

Is this an inference for regression test that you're doing?
 
Yes I think so.

Thread 'Deductive proof in logic formal systems'

I was reading documentation about the soundness and completeness of logic formal systems. Consider the following $$\vdash_S \phi$$ where ##S## is the proof-system making part the formal system and ##\phi## is a wff (well formed formula) of the formal language. Note the blank on left of the turnstile symbol ##\vdash_S##, as far as I can tell it actually represents the empty set. So what does it mean ? I guess it actually means ##\phi## is a theorem of the formal system, i.e. there is a...
