Problem 2 10 pt For the hypothesis test Ho 10 against Hi 10

Problem 2 (10 pt) For the hypothesis test Ho: -10 against Hi: > 10 with variance unknown and n-15, Use table V to approximate the P- value for each of the following test statistics. (1)t,-3.55 a. (2) to =-1.84

Solution

1) At t₀ = 3.55

P value using T Calculator (http://www.socscistatistics.com/pvalues/tdistribution.aspx) is

= 0.0016 (D.F = 14)

2) at t₀= -1.84

P value using T Calculator (http://www.socscistatistics.com/pvalues/tdistribution.aspx) is

p = 0.043532 (D.F = 14)
