Median lethal dose

emotions are never the same and so it is with other species such as mice or monkeys. This fact is due to the physical and psychological conditions and preparation of each subject. In her book In the Name of Science, F. Barbara Orlans, explains that the most common tests used to analyze the effectiveness or the safety of products are the Draize and the LD50. Both of them imply a large amount of pain to the animals and sometimes death. On one hand, the Draize test consists in applying possible toxic or irritant materials to rabbits that are conscious and healthy, in order to avoid those substances in future products. After the application, rabbits are examined regularly to find possible damage in their skin. On the other hand, the LD50, or median lethal dose, consist in determining the amount of substance that the subject needs to receive in order to cause death. In this second test half of the subjects die, and sometimes…

III. Identify statistical tools and methods to collect data: A. Identify Appropriate Family and Reason for Selecting it. To analyze A-Cap Corporation’s data, I will use measures of central tendency and distribution. Measure of central tendency is a measure used to describe the mean, median, and mode of a particular set of data while measure of distribution shows the skewness, kurtosis, and develops a hypothesis about a particular set of data. The reason I selected these two measures is that they…

In this category, I scored higher on the Internally Focused scale under the first contrasting pair, with a 59. Individuals in who exhibit this trait are immersed deeply in the complexities of their own feelings and thoughts. However, this trait is not very strong for me given that it is 10 points away from the 50th percentile of those who also possess this trait. Significant in this category are the scores for Imaginative/Intuiting and Feeling-Guided, having scored well above the Median on…

table as ‘With pressure’. Data: For this experiment, the data has been recorded in a table on paper and then entered into a spreadsheet. This was made into two different graphs, box and whisker plot graph and the arrow graph using the website NZ grapher. Analysis: The box and whisker plot graph above displays the minimum, lower quartile, median, upper quartile and maximum of the differences between the first time it takes the individual to write the required sentence (No pressure) and the…

Marilyn vos Savant said “Be able to analyze statistics, which can be used to support or undercut almost any argument.” (vos Savant, n.d.). In this particular instance one hopes to show how statistics support an argument on survey results for the Springdale Shopping area. The survey contained eight areas that will be discussed concerning different aspects of Springdale shopping area and what the statistic show. Also, a deduction will made as to which was the most and the least important to…

The Competitive State Anxiety Inventory-2 Revised (CSAI-2R), is one of the most frequently used instruments in the evaluation of situational anxiety in sports competition. Objectives: The objective of this study was to validate the Tunisian version based on the French version of the Competitive State Anxiety Inventory-2 Revised (CSAI-2R), including the direction and the frequency scales. Method: 418 athletes ranging in age from 14 to 34 years in different individual and team competitions,…

¥ For how many students do you have Verbal Aggressiveness scores? We have Verbal Aggressiveness scores for 59 students. ¥ What is the mean for the entire sample? The mean for the entire sample is 44.0169. ¥ How do you interpret the mean score? When we interpret the mean score, we should look at the minimum and the maximum scores, so we can see the mean are close to each one. In verbal aggressiveness, the minimum is 26 and the maximum is 65, which indicates that the mean around the middle of…

“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…

We can easily convert this into Cartesian form by replacing z by x+iy |(x+iy)-(-3 +2i)|=5 |(x+3) + i(y-2)|=5 √(〖(x+3)〗^2+〖(y-2)〗^2 ) =5 or 〖(x+3)〗^2+〖(y-2)〗^2=25 Which is the exact form of a Cartesian equation of a circle with a center of (-3, 2) and a radius of 5 We could check if a particular point lies on the circle Ex. z2=1-3i Substituting into the equation of the circle, with z replaced by z2=1-3i |(1-3i) - (-3 + 2i)|=5 |4-5i|=5 √(4^2+〖(-5)〗^2 ) =5 41=5, which is not true, thus z2 does not…
