Question

Find the following t-values in Table 4 of Appendix I. (Round your answers to three decimal places.)

(a)    t_0.05 for 5 df

t_0.05 =

(b)    t_0.025 for 7 df

t_0.025 =

(c)    t_0.10 for 18 df

t_0.10 =

(d)    t_0.025 for 32 df

t_0.025 =

Answer 1

Here all the t critical values by using t table

a] alpha = 0.05 df = 5

t _0.05,5 =2.571 (for two tailed test)

t _0.05,5 = 2.015 (for one tailed test)

b] alpha = 0.025 , df = 7

t _0.025,7 = 2.841 (for two tailed test)

  t _0.025,7 = 2.365 (for one tailed test)

c] alpha= 0.10 , df = 18

t _{0.1 ,18} = 1.734    (for two tailed test)

t _{0.1 ,18} = 1.330   (for one tailed test)

d] alpha = 0.025 , df = 32

t _0.025,32 = 2.352    (for two tailed test)

  t _0.025,32 = 2.037   (for one tailed test)
