Below are statistics I have managed to gather which shows the relationship between the variables of wfood,  totexp, income, age, nk.

The Null Hypothesis - H0: Correlation has risen by chance i.e. r = 0

The Alternative Hypothesis - H1: Correlation has not risen by chance i.e. r ≠ 0

*Exception: Reject H0 when P-value ≤ α = 0.05
