	Eagles Height in inches	Patriots Height in inches
Mean	73.51948052	73.94805195
Variance	7.095010253	7.786739576
Observations	77	77
Pooled Variance	7.440874915
Hypothesized Mean Difference	0
df	152
t Stat	-0.974858488
P(T<=t) one-tail	0.165589676
t Critical one-tail	1.654940175
P(T<=t) two-tail	0.331179353
t Critical two-tail	1.975693928

What can I conclude by this?

Answer 1

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

# Using pvalue :-

One tailed test:

P value= 0.165589676

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

Two tailed test:

P value=0.331179353

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

# Using t test table value

One tailed test

Calculated value=-0.974858488

Critical value= -1.654940175

Calculated value> critical value, Do not reject H0.

Two tailed test

Calculate value=|t|= 0.165589676

Critical value=1.975693928

Calculated value < Critical value

Do not reject H0.
