from this page http://www.mrc-bsu.cam.ac.uk/cochrane/handbook/chapter_12/12_4_2_p_values_and_statistical_significance.htm "In particular, P values less than 0.05 are often reported as “statistically significant”..."

jim_thompson5910 · Answer

if alpha is at its default value of 0.05, then that would point to choice C

jim_thompson5910 · Answer

oops i meant D...

konradzuse · Answer

that's kinda a dumb Q because what if alpha is 0.002?  LOL.

konradzuse · Answer

technically it could still be above Alpha :P.

TRHIS IS WHY STATS SHOULD EXPLODE.....

jim_thompson5910 · Answer

well if it's less than your set threshold, then it's significant which means you must reject H0

konradzuse · Answer

Stupid H0.... Stupid Stats.... :)

p<α -> significant (reject the null)
