Consider a random sample of size n from a normal distribution with unknown mean u and unknown variance o?. Suppose the sample mean is X and the sample variance is S?. We would like to test Ho : µ = µo versus H1 : µ + µo- What test statistic should you should use to test Ho versus H1? Select one: O a. N(0, 1) ~ O b. T = tn-1 ~ O c. W = (n-1)s Now suppose that n = 16, the observed sample mean i is 8.9. the observed sample variance sº is 25 and 40 = 10.5. What is the (appropriate) observed test statistic for testing Ho : µ = Ho versus H1 : µ # Ho? Give answer to three decimal places. What is the p-value of the (appropriate) observed test statistic for testing Ho : µ = Ho versus H1 : µ + po you just computed? Give answer to three decimal places.

Question
Consider a random sample of size n from a normal distribution with unknown mean u and unknown variance o?. Suppose the sample mean is
X and the sample variance is S?. We would like to test Ho : µ = µo versus H1 : µ + µo-
What test statistic should you should use to test Ho versus H1?
Select one:
O a.
N(0, 1)
~
O b. T =
tn-1
~
O c. W =
(n-1)s
Now suppose that n = 16, the observed sample mean i is 8.9. the observed sample variance sº is 25 and 40 = 10.5.
What is the (appropriate) observed test statistic for testing Ho : µ = Ho versus H1 : µ # Ho? Give answer to three decimal places.
What is the p-value of the (appropriate) observed test statistic for testing Ho : µ = Ho versus H1 : µ + po you just computed? Give answer to
three decimal places.
