Stoaches
Stoaches are fictional creatures distantly related to bigfoot and yeti.
Stoach weights are normally distributed, with a mean of 904g and a standard deviation of 104g.
State the probability that the sample mean of a random sample of 36 stoach weights exceeds 943g.
(Report the probability using at least four decimal places. )

Dr Math
the answer provided is different to the correct answer should be using the standard error as it's related to sample mean not mean as a whole therefore m = 904 g Standard deviations 104 divide by square root of 36 which is equal to 17.33333333 / 17.3333 (4d. p) then add to the calculator provided this number mean 904 standard deviation 17.3333 above 943 and the answer = 0.0122 (4.d. p)
