Computer Science: Data Processing Anela is a computer scientist who is formulating a large and complicated program for a type of data processing.

Anela has three ways of storing and retrieving data:

cloud storage, disk, or hard drive. As an experiment, Anela sets up her program in three different ways:

one using cloud storage, one using disks, and the other using a hard drive. Then Anela makes four test runs of this type of data processing on each program. The time required to execute each program is shown in the following table (in minutes). Use a 0.01 level of significance to test the hypothesis that the mean processing time is the same for each method.
