Statistical dispersion

More than 65% of ovules were just enlarged without undergoing callus or shoot phase independent of the sucrose concentration. Rest of the ovules was either with no development or dead after 8 weeks of culture period. The effect of sucrose concentration on ovule response was not pronounced (Table 18). When comparing the suitability of sucrose concentrations (2% or 4%, 4% 0r 6%, 2% or 6%) for ovule culture depending on the genotype, there is no significant difference for both genotypes on whatever…

Regression Method Based on the data we collected, our expected regression equation is: Walmart revenue = β0 – β1CPI + β2CSI + β3ECOM – β4GAS + β5POP –β6INT – β7UNEMP + β8EARN Then we ran the regression on Minitab and got an actual regression equation. We used the method (i.e. five questions and nine problems) to evaluate the equation Minitab produced. For each of the nine problems, we ask five questions: What is the problem? How can I detect it? What are the consequences of the problem? What are…

existing supplier’s rivets. Specifically this is done by comparing the diameters of the two groups of rivets. After collecting data a 95% confidence interval was computed and a statistical test was performed to determine if the average diameters of the two groups of rivets are the same. Conclusions from both statistical techniques led us to believe that both rivet suppliers on average provide rivets with about the same diameters. Therefore supplier with less expensive rivets should be…

Allgemeinversicherung (DAV) is using statistical process controls (SPC) due to DAV Kundendienstgruppe (DAKG) having issues with data entry of policyholder’s applications lack of quality and technical issues. One area of customer service that required improvement overall at DAV was the ability to process information and data without mistakes, as well as retrieving it in a timely fashion. In order to do this, DAKG started measuring quality by using Statistical Process Control (SPC), which was…

Introduction Strength is an abstract parameter that consists of many variables that can potentially influence the amount of force being exerted with certain individuals. In another word, strength represents the ability of extortion or endurance. Grip strength is subject to many health concerns and body mass index are few of the factors that could potentially influence the strength of individuals. And that throughout many studies gender and age correlation with grip strength could range from…

Amgis, a flavors and food additives company has a sudden surge in production due to increase in sales and transfer of production from an affiliate. The company requires additional labor to cope with the sudden increase in production. However, strict labor laws have limited the company to hire permanent employees, and overtime employees and forced them to engage temporary labor to keep the process flowing. The company then had to make arrangements with a third party labor provider and the…

correlation for both of them. The results were expected to have a high statistical significance relating to our R-squared value and adjusted R-squared. In addition to this, it was expected that the coefficient would higher for higher education than lower education. The research proved that simple linear…

RAID level 5 works with any number of disk equal or greater than 3 and places a parity sum on one disks in the set to be able to recover from a disk failure. (Striped blocks with distributed parity.) The parity calculations are done in a RAID 5 set using XOR. We assume a small RAID 5 set of four disks and some data is written to it. On the first three disks we have the binary information 1010, 1100 and 0011, here representing some data, and now calculate the parity information for the…
