Question

Identify the t-value whose number of samples n = 25, area = 0.01

n = 30 area = 0.005

n = 27 , area = 0.0025

n = 35 area = 0.0010

USE A SHORT BOND PAPER

n = 40 area = 0.0005

Answer 1

a.

$$df=n-1=24,$$

$$t=-2.492159$$

$$P(t<-2.492159)=0.05$$

b.

$$df=n-1=29,$$

$$t=-2.756386$$

$$P(t<-2.756386)=0.005$$

c.

$$df=n-1=26,$$

$$t=-3.066909$$

$$P(t<-3.066909)=0.0025$$

d.

$$df=n-1=34,$$

$$t=-3.347934$$

$$P(t<-3.347934)=0.0010$$

e.

$$df=n-1=39,$$

$$t=-3.55812$$

$$P(t<-3.55812)=0.0005$$
