Answer #1

Solution :

Given that,

(a)

sample size = n = 38

Degrees of freedom = df = n - 1 = 38 - 1 = 37

= 0.01

t ,df = t 0.01,37 = 2.431

critical t score = 2.431

(b)

sample size = n = 10

Degrees of freedom = df = n - 1 = 10 - 1 = 9

= 0.005

t ,df = t 0.005,9 = 3.250

critical t score = 3.250

(c)

sample size = n = 2

Degrees of freedom = df = n - 1 = 2 - 1 = 1

= 0.05

/ 2 = 0.05 / 2 = 0.025

t/2 ,df = t 0.025,1 = -/+12.706

critical t score = -12.706 , +12.706

(d)

sample size = n = 13

Degrees of freedom = df = n - 1 = 13 - 1 = 12

= 0.10

/ 2 = 0.10 / 2 = 0.05

t/2 ,df = t 0.05,12 = -/+1.782

critical t score = -1.782 , +1.782
