![1 Case 1: Machine Maintenance
2 A cereal company wants to make sure the machine used to fill boxes of cereal is working
3 properly. The machine is supposed to fill each box with 18 ounces of cereal. To test the
4 machine's accuracy, you sampled the weight of 40 boxes of cereal. To determine if the
5 machine needs maintenance, you conduct a one-sample t-test (see results in K2:M7). If the
6 average weight statistically differs from 18 ounces, you will order a maintenance repair. But
7 because the repair can be costly and because there are potential punitive costs for not
8 selling food products at the advertised weight, you want to be 95% confident in the results.
