Sample size

Question How does changing the size of the airplane affect how far the airplane goes. Hypothesis If we change the size of the airplane then the paper airplane will go further. Materials Paper, graph paper, meter stick, a pencil, Procedure: 1.I will build two identical paper airplanes. One will be my control airplane that is smaller and the other will be my test airplane the one that is bigger. 2.I will throw my control plane 10 times and I will use a meter stick to measure the distance of…

Darley (1968) that as the number of participants increased, help would become less likely was somewhat supported. The results in the graph Percentage of people who helped/did not help highlighted that the bystander effect occurred as the smallest group size had the highest help rate of 100%, and the percentage of participants who helped in the group of 19 was higher than that of the group of 35, 10.5% and 2.90% respectively. However, the groups of 3 and 10 did not support the hypothesis as they…

In relation to the first question, the results showed that subjects in the control group rated their experience somewhat negatively. Subjects in the one dollar category rated their experience statistically more positively in comparison to the control group while the twenty dollar category’s average rating was only minimally higher than that of the control group. Participants in the one dollar group also responded more positively when asked about their willingness to participate it similar…

5 from the textbook explain why we have a “big mess” of our free space memory allocation Answer: Below figure show one example of putting the memory. Quoted: ARPACI-DUSSEAU. R., ARPACI-DUSSEAU, A. (2012, ch17-8) In above example, assume total size is 4096, header eat 16k, each chunk total eat 108k (100 + 4 k header + 4 k chunk). In theory (assume perfect allocation), no waste space resulted. Then total 37 chunk block (108k) can be fitted. However, the splitting and coalescing mechanism made…

decisions. The various preferences should be weighted against each other and a percent importance should be applied to that characteristic as its weighting factor. All weighting factors should sum to 100%. A baseline technology should be selected with which to compare all the other technologies or solutions. A variance factor between the baseline and the alternative is assigned and put in the appropriate cell. Commonly -9, -3, -1, 0, 1, 3, 9 are the assigned variance levels. The assigned…

questioning and would use a similar tactic. Below I choose the question using this style focused on the area of racial discrimination as it is currently a hot topic and as a business major would affect my future organization. For instance, here is a sample question I would ask to find out how one felt about racial equality within their organization: a) Use the following scale to respond to each item on this survey. Response Scale: 1 = Strongly Disagree 2 = Disagree 3 = Agree 4 = Strongly…

its production line workers. A random sample of 71 production line employees were chosen for the survey and the test data results were collected accordingly. The resulting data also includes whether each employee in the sample took a statistics course or not. Ace would like to examine this data in order to prepare analysis report to the management team. Statistical Results 1. In this study of test scores and took statistics course, each variable in the sample data is characterized by creating…

Describe the sampling strategy. How appropriate were the various sampling design decisions? The sampling strategy is the first most important part of conducting this kind of research. According to Cooper and Schindler (2014) the most important characteristic of a sampling is to determine whether it represent the population it is supposed to represent. According to the article, “McMahon Group distributed mail surveys to 1,650 members and their spouses in January 1999” (Cooper & Schindler, NCRCC:…

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,…

“The golden ratio is a special number found by dividing a line into two parts so that the longer part divided by the smaller part is also equal to the whole length divided by the longer part.” (Elaine J. Hom )After the 21st century, golden ratio represents as a phi in Greek alphabet. The equation for golden ratio is a/b = (a+b)/a = 1.6180339887498948420 …,but if we round it two places, it will be 1.62.the golden ratio is also called the golden mean, golden section, golden number and so on. The…
