Question 1: A manufacturing company conducted a consumer survey on two popular products of one of their brands. Customer's opinion data are collected on a 10-point scale to measure customer satisfaction. The data are presented below: Customer No 1 2 4 S 6 7 8 9 10 Product Category 2 2 2 Yearly Income 190,000 85,000 100,000 80,000 75,000 80,000 120,000 200,000 40,000 56,000 Product Lifetime 7 5 5 9 6 14 5 4 5 Opinion Score 6 5 00 00 8 8 6 9 9 5 Part a) Determine the type of four given variables (Category, Income, Lifetime, Score). Part b) Compute mean, median, and mode for Score variable. Part c) Use two variability measures to show income variations of the customers. Part d) Fit the most appropriate normal distribution for Product Lifetime. Part e) Use correlation analysis to analyze existence of any relations between product, customer specification and customer satisfaction. Part f) Calculate Euclidean distance between customer 3 and 8. Question 1: A manufacturing company conducted a consumer survey on two popular products of one of their brands.
