How long it takes paint to dry can have an impact on the production capacity of a business. An auto body & paint business invested in a paint-drying robot to speed up its process. An interesting question is, "Do all paint-drying robots have the same drying time?" To test this, suppose we sample five drying times for each of different brands of paint-drying robots. The time in minutes until the paint was dry enough for a second coat to be applied was recorded. Suppose the following data were obtained. Robot 1 Robot 2 Robot 3 Robot 4 128 143 133 150 136 133 143 142 135 143 138 134 125 145 137 141 136 126 124 148 At the ? = 0.05 level of significance, test to see whether the mean drying time is the same for each type of robot. Find the value of the test statistic. (Round your answer to two decimal places.)   Find the p-value. (Round your answer to four decimal places.) p-value =

Lean Production

The word lean refers to the “slim “that is used in manufacturing for the systematic designing that focuses on minimizing the waste in the manufacturing or production with the constant productivity of the operation. Lean manufacturing was rooted from Toyota Production system a Japanese manufacturing company that works on the approach of minimizing the non-value-added activities and making the production lean.
