Companies that sell groceries over the internet are called e-groceries. Customers enter orders, pay by credit card, and receive goods by truck. A potential electronic grocer analyzed the market and determined that to be profitable, the average order would have to exceed $85. To determine if an e-grocery store is profitable in a large city, the service is provided to a random sample of customers and the size of the orders is recorded. From these data, can we infer that an e-grocery store will be profitable in this city? Sample statistics: X = 89.27, s = 17.30, n = 85, a = 0.05
