Use computer software packages, such as Excel, to solve this problem. The Jacobs Chemical Company wants to estimate the mean time (minutes) required to mix a batch of material on machines produced by three different manufacturers. To limit the cost of testing, four batches of material were mixed on machines produced by each of the three manufacturers. The times needed to mix the material follow.

Use calculator or Excel to solve the following problems. DO NOT USE MINITAB (except e). Do NOT use Excel built-in functions or solvers (except t.inv() and f.inv() to obtain critical t and f values). The tensile strength of Portland cement is being studied. Four different mixing techniques can be used economically. A completely randomized experiment was conducted and the following data were collected: Technique Tensile Strength Tensile Strength Tensile Strength Tensile Strength 1 3129 3000 2865 2890 2 3200 3300...

In order to compare two computer software packages, a manager has 15 individuals use each software package to perform a standard set of tasks typical of those encountered in the office. Of course, in carrying out the comparison the manager was careful to use individuals who did not have an established preference of skill with either type of software, and 15 individuals were randomly selected to use software A first while the other 15 used software B first. The time...

An airline wants to select a computer software package for its reservation system. Four software packages (1, 2, 3, and 4) are commercially available. The airline will choose the package that bumps as few passengers, on the average, as possible during a month. An experiment is set up in which each package is used to make reservations for 5 randomly selected weeks. (A total of 20 weeks was included in the experiment.) The number of passengers bumped each week is...
