Using the chi-square table determine where the p-value would be, for the data having df and computed value is 20.36 Answer 5 b. Using the chi-square table determine where the p-value would be, for the data having df 4 and computed value is 3.33 Answer: c. For a Two tailed test, if the df is 6 and the computed T value is 30.76, how do you represent the P value Answer d. For a one tailed test, if the df is 11 and the computed T value is 0.85, how do you represent the P value Answer e. Using the table F(1,8) determine where the p-value would be for the computed value of 30.0 Answer f. Using the table F(3,4) determine where the p-value would be for the computed value of 2.50 Answer

Answer 1

Solution:-

39)

a) p-value = 0.01

D.F = 5

X² = 20.36

P(X² > 30.6) = 0.01

p = 0.001 1.581 4.743 7.906 11.07 14.23 17.39 2 X*-20.36

b) p-value = 0.504

D.F = 4

X² = 3.33

P(X² > 3.33) = 0.504

p = 0.504 1.414 4.243 7.071 9.899 12.73 15.56 18.38 2 x 3.33

c) P(- 30.76 < t < 30.76) = less than 0.00001

D.F = 6

t-value = 30.76

P(- 30.76 < t < 30.76) = less than 0.00001

d) P( t > 0.85) = 0.207

D.F = 11

t-value = 0.85

P( t > 0.85) = 0.207

p 0.207 -4 -1 3 4 t 0.85

e) P(F> 30) = 0.001

DF₁ = 1

DF₂ = 8

F-value = 30

P(F> 30) = 0.001

р-0.001 3.475 4.865 6.255 7.645 9.035 F 30 0.695 2.085

f) P(F> 2.5) = 0.199

DF₁ = 3

DF₂ = 4

F-value = 2.5

P(F> 2.5) = 0.199

p 0.199 0.984 2.953 4.921 6.89 8.859 10.83 12.8 F 2.5
