	Eagles Age	Patriots Age
Mean	27.76662516	28.15171678
Variance	12.09082453	12.65872713
Observations	77	77
Pooled Variance	12.37477583
Hypothesized Mean Difference	0
df	152
t Stat	-0.679243926
P(T<=t) one-tail	0.249008166
t Critical one-tail	1.654940175
P(T<=t) two-tail	0.498016332
t Critical two-tail	1.975693928

What can I concluded by this?

Answer 1

Consider level of significance = [\alpha] = 5%= 0.05

# Using pvalue :-

One tailed test:

P value= 0.249008166

P value >0.05 , do not reject null hypothesis(H0) at 5% level of significance.

Two tailed test:

P value=0.498016332

P value>0.05 , do not reject H0 at 5% level of significance.

# Using t test table value

One tailed test

Calculated value=-0.679243926

Critical value= -1.654940175

Calculated value> critical value, Do not reject H0.

Two tailed test

Calculate value=|t|= -0.679243926

Critical value=1.975693928

Calculated value < Critical value

Do not reject H0.
