Highway paving Inc. is a company specializing in residential road surfacing. Many of its clients seek out its specialized products. Recycled rubber can be added to asphalt mixture to reduce road noise which appeals to environmentally conscious clients.

However the viscosity (resistance of flow) must be maintained within very tight limits otherwise it may be too thick or too watery. The goal is a viscosity of 3200.

During the manufacturing of each batch of asphalt, the quality control specialists takes 15 samples of the material and tests the viscosity. This also ensures the batch has uniform viscosity. Calculate σ_x̅.
