A quality control inspector has taken four samples with five observations each at the Beautiful Shampoo Company, measuring the volume of shampoo per bottle. If the average range for the four samples is 0.4 ounces and the average mean of the observations is 20.0 ounces, develop 3-sigma control limits for the bottling operation. (Round answers to 2 decimal places, e.g. 15.25.) CL UCL LCL

Two independent samples have been selected, 67 observations from population 1 and 94 observations from population 2. The sample means have been calculated to be x¯1 = 9.9 and x¯2 = 10.2. From previous experience with these populations, it is known that the variances are σ21= 39 and σ22 = 38 (a) σ(x¯1−x¯2). answer: _____ (b) Determine the rejection region for the test of H0:(μ1−μ2)=2.94 and Ha:(μ1−μ2)>2.94 . Use α=0.02 z > : _____ (c) Compute the test statistic. z= (d) Construct a...
