Statistics K501 is kicking my ass tonight. Would it really be so freaking hard to explicitly say that if the standard deviation of the population is unknown, you can use the standard deviation of the sample to calculate the standard error? For f*cking out loud, I’d still be on question 4 if it weren’t for Wikipedia.

And it’s impossible to do a gut check on whether these answers are right when the book fails to tell you the significance of the values. Woo boy, now I know the t value with 45 degrees of freedom. What the hell does that mean??

Homework’s due Wednesday night. Seriously, if you’re an expert and want to help, I’m sure we can work out some sort of exchange of goods or services. Just think: there’s a Paul Janish-autographed baseball that could be yours!
