Question

A)

You will be asked to determinethe correct prob-value in each of the following situations. You may assume data sets are normally distributed. (3 pointseach)

a. A right-tailed test withz = 1.43 based on a sample larger than 50.

b. A two-tailed test with t= -1.443 based on a sample of size 16. (To match my answeryou will need to use Minitab to get this value.)

B)

You will be asked to determinethe correct critical value(s) in each of the followingsituations. You may assume data sets are normallydistributed. (3 points each)

c. A two-tailed test with a= 0.10 a known value of s.

d. A left-tailed test witha = 0.10, unknown s, and a sample of size 23.

Explanation / Answer

A) a) The P- value of a right-tailed test with z =1.43 based on a sample larger than 50 = 1 - 0.9236 = 0.0764      b) The P- value of a two-tailed testwith t = -1.443 based on a sample of size 16 = 2 * 0.0848 =0.1696 B) c) The critical value(s) of a two-tailed test with = 0.10 a known value of are -1.645 and 1.645      d) The critical value(s) of aleft-tailed test with = 0.10, unknown s, and a sample ofsize 23 = -1.321
