the oil/inflation one was just a plug and chug. the change in oil was -7 and then i took 4.85% from the chart they had- don’t remember the exact answer but it worked out fine to one of the answer choices.
t stat i didn’t know, took a guess. r i got wrong which is just upsetting, no negative sign for me. the conf interval i only did one std dev not 2. got -.43. what was the last one?
quant hurt- i thought i had done fine until i came back to AF. ouch.
