Stoaches

Stoaches are fictional creatures distantly related to bigfoot and yeti.

Stoach weights are normally distributed, with mean 904g and standard deviation 104g.

State the probability that the sample mean of a random sample of 36 stoach weights exceeds 943g.

(Report the probability using at least 4 decimal places. )

Correct result:

p =  0.2853

Solution:

m=904 g d=104 g  p1=N(m,d,X>943g) p1=0.2853  p=p1=0.2853
