a sample of 16 egg is take froom normal disribution. variance is unknown
sample mean xbar is 4.49 and sample st dev, s, is 1.231
you wish to do a test if the population mean is less than 5
state h0 and h1, calculate test statistic and use the t disribution to find what level you can accept or reject h0.
now i think the h0 is populationmean=5, h1 not equal 5?
test statistic, t=(xbar-5)/(s/root of n)
which i make =-1.657 please tell me if this right because if its wrong my lookup table will not even help..
so now what i do with the t disribution table because i am confuse. i know degree of freedom is n-1 = 15. but i am confuse.
