Pre-Lab Questions 1. A population is a group of the same species that live in the same area and sometimes compete or can mutually benefit one another. A group of organisms will only be considered a population if they live in the same area in space and time. N is the true population size for a given group of organisms. This number is unlikely to be completely known. Whereas N hat is an estimate of population size. 2. There are two methods of sampling, direct and indirect. Direct sampling is an…

Problem 1.17 In problem 1.17, the average age of pinon trees in the coast ranges of California was investigated. 500 ten-hectare plots randomly selected using a computer. The age of every pinon tree within each plot was measured and the average age of the plot was used as the unit measurement (Whitlock and Schluter, 2015, pg 20). The results of this investigation were used to estimate the average age of California pinon pines, making the population of interest in this study is all California…

For example, if σ = 45% and ρ = 0.2, then the standard deviation with 50 stocks would be 20.91%, and would rise to 22.05% when only 20 stocks are held. Such an increase might be acceptable if the expected return is increased sufficiently. Hennessy could contain the increase in risk by making sure that he maintains reasonable diversification among the 20 stocks that remain in his portfolio. This entails maintaining a low correlation among the remaining stocks. For example, in part (a), with ρ = 0…

Imagery ability A pre-experiment questionnaire was administered to establish the participants’ imagery ability prior to the imagery intervention. Questions focused on how easy it is for the participant to image and the vividness of these images. For example, how easy is it for the participants to image staying positive after setbacks. This helped to control for potential confounding variables as research has shown imagery ability influences the effectiveness of imagery (Gregg, Hall, McGowan, &…

Standard Oil was the leading supplier of oil to the United States in the 1880’s. The Company was run by John D. Rockefeller. Rockefeller became one of the richest and most powerful men in America. Rockefeller tried to get Standard Oil to be the only supplier of oil in North America. Rockefeller believed that he could operate his company around the regulations set by the United States Government, and that he could get away with it. “President Roosevelt said confidently that no man, no matter how…

We have all heard about global warming. Still we hear debates on whether its effects are real or not. Most people today believe that it is a real thing, but cannot accept that it is something that will affect their lives. People are always looking in the short run for what will make their lives more convenient and get them through their day easier. Jared Diamond, a Professor of Geography at UCLA and Pulitzer Prize winner, wrote an essay in Time magazine addressing how our actions affect us. He…

The preeminent design of the paper helicopter experiment would comprise of the best mean and standard deviation of the overall measured data. An in depth comparison of the mean value and the standard deviation of each variable will be discussed in relation to a measure suitable for a longer flight time and a more accurate landing. These variables will be discussed relevant to the data and information gathered from our experiment during testing. The ratio of each helicopter will be discussed in…

.542, .526, and .441. The statistics for these numbers are .499 for the mean, .498 for the median, no mode, .0389 for the standard deviation, and .499 ± .0389 for the best answer. The Rf values for the dyes of the green skittles are .621, .455, .628, .590, and .397. The statistics for these numbers are .538 for the mean, .590 for the median, no mode, .105 for the standard deviation, and .538 ± .105 for the best answer. The Rf values for the dyes of the orange Skittles are .284, .271, .321,…

There was also the outliers in the graphs in which was the thirty seven and forty nine because that was the maximum amount that people declared that they went too which was not close to all the other points that were adjacently grouped together. The standard deviation for all these plots is 7.97 in which makes the interquartile rage be interpreted in the box plot, Q1 is 6 and Q3 is 13. Some of the interferences that can be drawn would be the Q3 because of the larger points, the Q3 is then more…

There are two main viewpoints on any environmental issue, the modernist perspective and the neo-traditionalist perspective. The two perspectives greatly contrast each other, as they take completely opposite sides of the argument in any environmental issue. This was represented in the lecture by Professor Mark Boyer about Considering Environmental Values. For the purpose of this essay, I will specifically be talking about the issue of Climate change, and how both perspectives view this…
