P(T<=t) two-tail	0.286415763
t Critical two-tail	1.975693928

Conclusion of this t-test? What can I concluded by this?

Answer 1

Consider level of significance == 5%= 0.05

# Using pvalue :-

One tailed test:

P value= 0.143207882

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

Two tailed test:

P value=0.286415763

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

# Using t test table value

One tailed test

Calculated value=-1.069776516

Critical value= -1.654940175

Calculated value> critical value, Do not reject H0.

Two tailed test

Calculate value=|t|= 1.069776516

Critical value=1.975693928

Calculated value < Critical value

Do not reject H0.
