I know it is only 3 questions max or whatever but I really need help doing this. I would love a walk through / explanation and I'm sure a bunch of other students would as well! Charge me for extra questions if need be but I need help on this please!

LED Light Testing - SPC Case: A small specialty light manufacturer has inputs of 150 units of their 4000 K LED lights every hour. Every light is tested during production using both variable and attribute measures. Measurements are taken at two different stages. The first test comes after a partial assembly stage to determine how many units do not light up. If the assembly lights up it moves through the remaining stages. Test two measures Lumens (brightness), and test three measures Kelvin temperature (light color) for a fully assembled bulb at the end of the manufacturing process. General directions: Read all of the directions before starting Include all math, tables, and graphs on this sheet only Make a copy of the front and back of this sheet before starting Write your name in the front top right corner of this sheet All work shall be performed by hand . Problem directions: The table contains the results of the first test Round to the fourth decimal place (0.0000) Complete the table (on the reverse) based on the chart type required for this analysis Draw a chart reflecting on the reverse) the points, process mean, UCL, LCL, Zones A, B, &C . Calculate the following for the first test: 1. Process mean (calculate the mean using two methods to check your work) 2. Upper Control Limit @ 3 Standard Deviations 3. Lower Control Limit @ 3 Standard Deviations Answer the following: 1. Is the process currently in control or is there a need for concern? In detail, explain your determination. 2. Evaluating all of the results in the table, should a Six Sigma team analyze the process for improvement? In detail, explain your response.
