Statistical dispersion

Results When we look at the results we must compare a native to a non-native to determine if the hypothesis is true. We determined earlier that we will compare American holly with Japanese privet, red bay with Florida anise tree, and kalmia with rhododendron. The American holly seemed to have more healthy leaves than the holly but not by much. The holly had 127 leaves with no damage while the privette had 139 leaves with no damage. The holly then had 97 leaves with less than ten percent damage…

be included and analyzed in order to minimize sampling error. Sample size G, of 40,000 centimeters squared, provides the most information about species richness. Due to the fact that it is the largest representation of a habitat. A t-test is a statistical analysis that compares the means of two populations, wherein the variances of the data determine whether or not the means differ significantly. From a t-test a null hypothesis can be determined. The null hypothesis for this study is the mean…

The two-sample t procedure is appropriate to use in this experiment in order to see if there is a difference in the two population means of stride length in the two different species, N. rattus and N. squamipes. This is because the boxplots appear to be roughly symmetrical, as well as, both normal quantile-quantile plots look roughly linear. Considering two-sample t-procedures are quite robust to violations of the normality assumption, the t-procedure will likely perform well in this…

Life after High School This investigation was to find the change in future aspiration of high school seniors in the US after 9/11. The suggestion was that the economic impact of the attack would cause fewer childten to have the means to enroll in college. However some where divided on the impact it would have on enlistment as wether it would increase due to patriotistic sentiment or decrease with them rise in probability of actual engagement. An unidentified polling organization arranged…

The results of analysis on table 1 presented the demographic characteristics of cattle farmers in the study area. A large proportion were male (95.9%) than the female (4.1%), which is an indication that male participated more than female in the awareness and the use of crop residue urea feeding technology. The findings also revealed that majority (40 – 50 years) of cattle farmers are in their middle ages which implies that age was an important variable as it reflects the physical strength for…

A small burette funnel was filled with column packing solvent at mobile phase, high boiling petroleum, in this case hexane (and then 10%acetone hexane mixture), and Alumina as stationary phase. When adding the sand and the alumina they have to be first mixed with the hexanes in order not to disturb the column. The Lycopene is Red- Orange and more attracted to alumina due to its high degree of Unsaturation, which can be expected to be eluted after Yellow-Orange Carotene pigments. And the other…

When it comes to individual, everyone has different levels of ability to deal with memory. In reality, you will find many women complaining that their husbands or boyfriends tend to forget their birthdays and anniversaries; and men always explain that they have bad memories. So, is it true that women have a better memory than men? Dose gender affect memory? The evidence shows that gender dose affect memory. In fact, men and women are equally affected by short-term memory loss. Nevertheless,…

cultures recognize that as customer relationships are vital to success, the customer is actually driving the organization. If you do not provide what the customer expects someone else will. Statistical Process Control (SPC): SPC might aid in identifying areas for future improvement. It involves using statistical analysis to identify process variation. Common cause variation: This is the variation that is inherit to a process or system- always present- as a result of the combinations of…

Caffeine Impact on Goldfish Metabolism Introduction Metabolism is a process that enable organisms to maintain their life. Metabolism can be measured in numerous parameters. Within this experiment in order to measure the metabolism rate by determined the level of dissolved oxygen. Goldfish is an example of poikilotherm that are organisms that are influenced by the environment surrounding them. Thus, the manipulation of surrounding can influence the metabolism rate due them being ectotherms.…

patient with the high number of visits is affected by the age of the patient. Hypothesis: HO: The older the patient is, the lower the numbers of visits are per year Ha: The older the patient is, the higher the numbers of visits are per year Statistical Analysis…
