Delta Food Grocery has two grocery stores located in Bije City. One shop is located on Jalan Usman and the other on Jalan Sinda and each is run by a different manager. Every manager claims that his shop layout maximizes the number of impulsive customers. The two managers surveyed their sample of customers and asked them how much they were spending than they planned, in other words, how much they were spending on impulse (spending more than they planned). The following table shows sample data collected from the two shops. Jalan Usman (Rp 000) Jalan Sinda (Rp 000) 15.78 15.19 17.73 18.22 10.61 12.87 15.79 17.79 13.45 13.96 12.85 13.74 12.47 10.83 S1 = 2.5529 S2 = 2.5675 Top management at Delta Foods Grocery wanted to know if there was a difference in the mean amount of impulsive consumption between the two stores. Perform statistical analysis via: 1. Compile the null hypothesis and alternative hypothesis 2. Help both managers test their hypothesis, Use alpha = 0.05 3. What is the conclusion
