if i have k = 36.86 +/- 4.78 and v = 113 +/- 9.92 both using 95% confidence limits and no true values of k or v given am i right in saying that accuracy cannot be determined and that v is a more precise measurement my question was to comment on what can b...

can you explain how you got x = a(2)^(-t/T) from the information in the question and the original equation ln(a/x)= (t/T)ln2 not ln(x/a) = (-t/T)ln2 which is what you had??

thanks
