Question

Which of the following t scores would significant at the P<0.05 level not the P<0.01? There is more than 1.

Select one or more:

a. t = 2.89, df = 14

b. t = -2.87, df = 27

c. t = -2.17, df = 17

d. t = 3.52, df = 9

e. t = 2.68, df = 60

f. t = -2.93, df = 19

Answer 1

SOLUTION-

STEPS: P-VALUE CALCULATOR> ENTER THE T-SCORE> ENTER THE DF> ENTER THE LEVEL OF SIGNIFICANCE> OK

1.) T= 2.89 AND D.F= 14

AT 0.05, P-VALUE = 0.012, SIGNIFICANT AT P<0.05

  AT 0.01, P-VALUE = 0.012, NOT SIGNIFICANT AT P<0.01

2.) T= -2.87 AND D.F= 27

AT 0.05, P-VALUE = 0.008, SIGNIFICANT AT P<0.05

AT 0.01, P-VALUE = 0.008, SIGNIFICANT AT P<0.01

3.) T= -2.27 AND D.F= 17

AT 0.05, P-VALUE = 0.044, SIGNIFICANT AT P<0.05

AT 0.01, P-VALUE = 0.036, NOT SIGNIFICANT AT P<0.01

4.) T= 3.52 AND D.F= 9

AT 0.05, P-VALUE = 0.006, SIGNIFICANT AT P<0.05

AT 0.01, P-VALUE = 0.006, SIGNIFICANT AT P<0.01

5.) T= 2.68 AND D.F= 60

AT 0.05, P-VALUE = 0.009, SIGNIFICANT AT P<0.05

AT 0.01, P-VALUE = 0.009, SIGNIFICANT AT P<0.01

6.) T= -2.93 AND D.F= 19

AT 0.05, P-VALUE = 0.008, SIGNIFICANT AT P<0.05

AT 0.01, P-VALUE = 0.008, SIGNIFICANT AT P<0.01
