Similarly the first quartile can be defined as 1/4 of the way through the sorted data, and the thirdly quartile to be 3/4 of the way through the sorted data. Second quartile is also known as the median. The range between the first and third quartiles includes half of the data. The sizing of the range (i.e., the difference between the third quartile and the first quartile) is another measurement of variability called the inter-quartile range or IQR. For normally distributed data IQR = 1.35 From the above calculations it appears the reorganization recitation has not been a grand success. Though it appears to have tightened some loose ends but still the average output remains the same.Task-3Table-2 Annual record of gross revenue revenue & advertising expenditure for SarnesCo (000s)Period123456789101112Sales Revenue100 one hundred thirty160175180190190180220250255260Ad vertising expenditure1012121213131314151516163 menstruum moving averages for sales A3 = (160+130+100)/3 = 390/3 = 130A4 = (175+160+130)/3 = 465/3 = 155A5 = (180+175+160)/3 = 515/3 = 171.67A6 = (190+180+175)/3 = 545/3 = 181.67A7 = (190+190+180)/3 = 560/3 = 186.67A8 = (180+190+190)/3 = 560/3 = 186.67A9 = (220+180+190)/3 = 590/3 = 196.67A10 = (250+220+180)/3 = 650/3 = 216.67A11 = (255+250+220)/3 = 725/3 = 241.67A12 = (260+255+250)/3 = 765/3 = 2554 period moving averages for sales(it can be calculated similarly as above)A4 = Task-4Task- 5 Business PresentationMaterial for the presentationSarnesCo, the manufacturer of machinery for the textile industry, wants to ameliorate its assembly lineSarnesCo appoints consultant, who in turn study the assembly...The range between the first and third quartiles includes half of the data. The size of the range (i.e., the difference between the third quartile and the first quartile) is another measurement of variability called the inter-quartile rang e or IQR. For normally distributed dataTaking a look at the mean, median figures of the production skill before and after the implementation of these steps, it is quite apparent that the consultants have not been able to improve the assembly line as much as desired by the company.
