The Newtower Company has experienced a 3.2% rate of customer complaints and attempts to lower this rate with an employment training program. After the program, the complaint rate is dropped to 1.5%. For a sample of 250 customers, find the mean and standard deviation for the number of complaints in this group of 250 customers. o² = 250 x 0.015 = 3.75,0 = 1.936 μ = 250+ 1.5 = 166.67 μ=150 o² = 250 x 0.015 x 0.985 = 3.694, o = 1.922 0²= 250 x 0.15 x 0.85 = 31.875,= 5.656
