1. SohnCo. Engineered Systems has developed a solution to the problem of problem #1. They have developed a custom torque wrench (the SohnCo. 2025 robo-torque wrench) for golf cleats that installs the cleat and turns it to the appropriate tightness. The design specification for Jiang Sports America cleats is 10.5 inch-lbs plus or minus 1.2 inch pounds. The CEO of SohnCo. Engineered Systems is a competitor and a bit of a gambler. He offers a gamble to the CEO of Jiang Sports America. He offers a $100,000 prize if Jiang Sports America uses the SohnCo. 2025 correctly and in a test if Cpk is less than 1.5 than he pays the $100,000 to an agreed-on charity. If the SohnCo. 2025 meets the specifications and a C pk of 1.5 or greater, Jiang Sports America buys five of the SohnCo. 2025 machines. Below are some data from the agreed-on test: 25 subgroups of 4 pairs of shoes each.

(These data are also in the Excel file.)

Please assess the gamble. Did the SohnCo. 2025 meet the challenge? You must certify the Cpk and other aspects of the bet.

Suppose before the test, they took another action: $500 to charity per too loose spike and $300 per too tight (Torque too high) over the next 1000 pairs of cleats. Determine their total donation.
