Ambidexterity Amongst Students and Athletes MATH 141 (Prof. An) Final Project December 2015 Romeo Ardimento, Lorraine Jabouin, Christopher Kremer, Fiona Macleod Introduction/Background Being Ambidextrous can be quite useful; particularly for athletes and musicians. Many sports require the use of both hands, as do many instruments. For this reason our team decided to determine the difference in ambidexterity, if any, between people who are either athletes or musicians, and individuals who are not

Given: The use of electrical currents in physical therapy is a common practice. There are many different uses for electrical stimulation: it can be used to facilitate a muscle contraction, to decrease pain levels, to control edema, and to promote tissue healing.3 Neuromuscular electrical stimulation (NMES) is the use of an electrical current to facilitate a muscle contraction, usually for strength gains.3 Many different parameters of electrical stimulation have been evaluated to determine which one

Fries are one of the many trademark foods of McDonald’s restaurants, with millions of people flocking to their local McDonald’s every day to enjoy the delectable potato side dish. The fries are also quite cheap— only costing $1.39 for a small, or $2.29 for a large at McDonald’s in the United States (not including tax), making them a very desirable purchase. However, many may ask themselves if they are receiving an amount of fries that makes the low price actually “low,” especially when looking at

• Summary o The authors of this paper indicate an apparently novel method for improving the cellular uptake of DNA origami-based drug delivery nanocarriers. While the transport protein, transferrin (Tf), has been used to functionalize other types of drug delivery nanocarriers, it had yet to be incorporated into nanocarriers made via DNA origami prior to this publication. The authors demonstrate successful functionalization of Tf to a specific morphology of DNA origami using gel-shift analysis and

Tulving’s 1975 study. The aim was to investigate the effect of phonetic and semantic encoding on correct recognition of words. The research hypothesis was semantically encoded words have a higher rate of correct recognition then words that have been phonetically encoded. This was a one-tailed hypothesis, as previous research supported it. The null hypothesis was that the results will show no difference between words that are successfully recognised from the two levels of encoding, and any difference

interpretation of data structures which goes to invest in another primary objective; that of understanding the student’s attitudes and preferences to Middlesex University’s communications systems. * Mainly, to explore the reasons behind vivid statistical differences between different demographic groups. Due to the nature of the data sought and the fact that this remains quite an exclusive

1. Write a null and an alternative hypothesis for each of the following. Be sure to state each hypothesis in the context of the problem. A. A forestry textbook claims that the mean age of pine trees in Colorado is 30 years. You think the age is greater than that. (2 points) ans: Ho = mean = 30 the mean age of the pine trees is 30 years for Ho Ha : mean > 30 the mean age of pine trees is more than 30 years B. A brochure on anti-aging cream states that the mean age of people in the United

Another limitation to the study is the fact that the juveniles might not be aware of the previous incarceration status of their parents.

FINA 6204 Problem Set 1 The purpose of the assignment is to review basic hypothesis testing and regression techniques. There is an appendix in your textbook, Appendix C: Using Excel to Conduct Analysis, which may help you with running regressions in Microsoft Excel. You may also wish to use a basic statistics text for guidance if needed. I have also provided you with a table with the t distribution. If you have an older version of EXCEL and have not previously loaded the Analysis ToolPak
