Dear tutor, help me to solve below question from Six sigma.

Corporate wants all complaints closed in 90 days or less. Any complaint taking more than 90 days is not acceptable. There are five opportunities are available for not closing the complaints within 90 days. The company audit team has taken previously closed complaints and compiled the information regarding the number of days taken to close each complaint. The results are given below.

92, 62, 40, 30, 52, 82, 24, 60, 61, 20, 85, 68, 96, 68, 25, 55, 49, 97, 46, 54, 36, 65, 34, 99, 78, 36, 102, 70, 58, 46

Calculate DPU, DPO, DPMO and overall sigma level for the process (both short term & long term). Assume the data given above as long-term data
