To test Ho:u= 100 versus H1:u=/= 100, a simple random sample size of n= 20 is obtained from a population that is known to normally to be normally distributed. Answer parts (a)-(d).

If x= 104.5 and s= 8.5, compute the test statistic

T=______ (Round to three decimal places as needed.)

Solution

As

t = (X - uo) * sqrt(n) / s

and uo = 100, then

t = (104.5 - 100)*sqrt(20)/8.5

t = 2.368 [ANSWER]
