2 1 point Suppose you draw simple random sample of size 13 f

2. (1 point) Suppose you draw simple random sample of size 13 from a large population that has a Normal distribution.

You will use your test statistic value of 2.13 to test H₀:=₀ versus H_a: >_0.

a. Suppose you know the standard deviation of the population. Would the number 2.13 be a -test statistic or a -test statistic and what is the P-value for your test?

b. Suppose you do not know the standard deviation of the population. Would the number 2.13 be a -test statistic or a -test statistic and what is the P-value for your test?
