significant" mean?! HELP? Average total daily sales at a small food store are known to be $452.80. The store's management recently implemented some changes in displays of goods, order within aisles, and other changes, and it now wants to know whether average sales volume has changed. A random sample of 12 days shows xbar =$501.90 and s=$65.00. Using alpha level = 0.05 is the sampling result significant? Explain.
What does "is the sampling result significant" even mean ?? Is it trying to find out if the null hypothesis is rejected or accepted? I dont know what to do how do i do this?
