To Test :-

H0 :-

H1 :-

Test Statistic :-


t = 2.8912


Test Criteria :-
Reject null hypothesis if


Result :- Reject null hypothesis


Decision based on P value
P - value = 0.0202
Reject null hypothesis if P value < level of significance
P - value = 0.0202 < 0.05 ,hence we reject null hypothesis
Conclusion :- We reject H0

There is no sufficient evidence to support the claim that is no significant relationship between square footage and selling price.
