You're tasked to inspect the production process for any issues with a specific emphasis on the actual weight of the blade that's produced for the lawn mower. The blade weight data is given below & shows the recent production output. The firm has used a SPC chart that was developed when the process was stable & was established with the parameters of the process mean (x-2bar) being 5 lbs & the process moving range (mR) being 0.12 lbs. Given this, construct the appropriate control chart & assess the current state of affairs of the production process.

Focus on the blade weight from above, it had been determined that the mower will function as designed if the blade weight stays within a specified range. The noted range is a 10% leeway from the design weight of 5 lbs. Therefore, the specification for the weight is 5 lbs plus/minus 0.5 lbs. Knowing this & having the full process data, make an assessment of the process capability.
