P15.-Hypothesis-Testing-1S1T---Super-Market-Loyality-Program
1 Sample 1 Tail Hypothesis Testing
Population Parameters: Mean=120 Sample Parameters: n=80, Mean=130, SD=40, df=80-1=79 1-sample 1-tail ttest
Assume Null Hypothesis Ho as Avg spending <= $120. Thus Alternate Hypothesis Ha as Avg spending > $120.
As (p-value = 0.014) < (α = 0.05); Reject Null Hypothesis Thus Avg spending > $120; we can go ahead and launch Loyality program.
