electrodes in electrolyte, on the current flow through copper electrodes were tested. Table 1 and Graph 1 display the results when increasing electrolyte concentration. Evident in Graph 1, the results contained scatter, and consisted of an outlier in the sample in which the ratio of NaCl: deionised water was 10:30mL. The outlier and scatter may have been due to random errors, which caused the results to be unreliable. Due to this, the raw data does not support the hypothesis. Thus, a line of…

Problem Statement In hopes of increasing the customer count in their stores, the Allsup’s franchise has reduced prices on their coffee beverages. Based off a 34-store sample that is an almost exact mirror of all 316 stores, over the following four weeks, the chain has a gross margin of 42% and has increased their average customer count to 967. That being said, based off the statistical evidence found in hypothesis testing, we can concur that reducing the prices of coffee beverages has proven to…

Samples were only taken from The Harvesting Hope Program in Aurora IL. As a result, the sample cannot be a representation of the rest of the child homeless population. Homeless children in other programs may produce differing results. Also, using the intervention in another geographical setting does not ensure its effectiveness in that setting. The second limitation to this study is the sample size. The sample consists of 40 children in The Harvesting Hope…

DNA samples were extracted from sixteen unidentified shark tissue specimens and underwent PCR amplification of CO1 mitochondrial gene. DNA samples were assessed for presence and quality using agarose gel electrophoresis. Species identification was performed by importing finalized CO1 sequences into two DNA databases to ensure accurate identification. Phylogenic analysis was then conducted to determine relationships between identified species. Electrophoresis Electrophoresis of DNA run in 2%…

EL-Emir tested their accounts payable and supplier credits including supporting advertising credits, Nashwa credits and Zaki credits. 2. CASE ANALYSIS 2.1 Advertising Credits In this case, there were only 8 out of 2,500 confirmations were sent. The sample size was too small to assess the risks of material misstatement. Therefore, the number of the confirmations was insufficient. It violated the principle of sufficiency, which is one of the determinants of persuasiveness of evidence.…

in the field of surveying and conduct experiments used to improve methodology techniques. The methodology used by Gallup to conduct such surveys is top tier quality. Accurate and unique results are obtained from the sample weight applied to the sample, as well as the immense sample of individuals across nations.…

The experimental method and the statistical approach that was used to test the hypothesis are appropriate in terms of analyzing the correlation between branch diameter and pollen and seed producing cone sizes across conifer species. A similar paper that helps support the methodologies used in this article titled, “Branching habit and the allocation of reproductive resources in conifers” also used methods like Corner’s rule to analyze conifer’s reproductive…

First, the tissue was disrupted mechanically to acquire a crude homogenate containing buffers that keep the enzymes from degrading. Next, knowing that LDH was present in the cytosol, the sample was centrifuged and cytosolic enzymes including LDH were recovered from the supernatant. After centrifugation, the sample was exposed to different concentrations of ammonium sulfate in which the least soluble enzymes would precipitate out early and most soluble enzymes would precipitate late. Then, using…

(a) The researcher carried out this research is to show the importance of brand image benefits on satisfaction and loyalty. The evaluation of brand image benefits of the products help marketers to set up an effective marketing strategies. The results drop a hint that marketers should focus on brand image benefits in order to achieve customer loyalty. Besides that, it provides some suggestions to the marketers specifically for branding strategies based on the proposed model. According to the…

the plate and inoculated onto a slide for further microscopic observation. The hypothesis was not entirely rejected as certain unique traits of the microbe collected was identified closely to a bacterium, based on growth, round structure, and small size. Further experiments would need to be conducted in order to fully taxonomize the microbe as observations and the dichotomous key elimination some of the possibilities as to what the microorganism can be identified as. Introduction Living…
