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…

the blue Skittles are .498, .488, .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…

Equation of trendline 1 calculation: m= rise/run = 12/15 = 0.8 c= 5.9 y= 0.8x + 5.9 Equation of trendline 2 calculation: m= rise/run = 25/45 = 0.5 c= 17.6 y= 0.5x +17.6 Point of intersection: Equate both trendlines to find point of intersection 0.8x + 5.9 = 0.5x + 17.6 x= 39 Since x=39, x2= 9 as x2 represents x in descending order. R2: R2 for trendline 1 = 0.98 Correlation coefficient for trendline 1= 0.96 R2 for trendline 2 = 0.98 Correlation coefficient for trendline 2= -0.99 Ratio…

channels of 8 bit information. Thus, the pixel values vary from 0 to 255. Small training areas of around 300 pixels were selected from different land cover types from these 3 channels and also from the texture channels. Statistical data like Mean, Median and Standard Deviation is calculated and based on that, following conclusions were made. Numbe r of pixels 310 56 56.63 13.61 14.00 89.00 0 15 mean value Channe l 1: 6 July Channe 310 44 45.41 12.45 9.00 74.00 0 15 l 2…

Fig. (3-23) Extrapolate Resonance frequency (fo) map of Nile Delta Area Fig (3-24) is extrapolate contour map for Associated Amplification of ground motion (Ao) of Nile Delta Area , from this map we notice the following : A - The value of (Ao) in the Central, Eastern and Northern part of Nile Delta is the same in most points and varied from 4 to 5. B - The value of (Ao) in the North Western part of Nile Delta and Alexandria is the same in most points and varied from 5 to 7 and…

Lemma: If p > 3 is prime, then either p = 1 (mod 6) or p = 5 (mod 6). Proof: The residue classes modulo 6 partition Z, so any z in Z satisfies a congruence z = n (mod 6) where n is in {0,1,...,5}. z is divisible by 6 if n = 0, 2 if n = 2, 3 if n = 3, and 2 if n = 4. These cases cover the primes z = 2 and z = 3; if z > 3 is prime, it follows that n = 1 or n = 5, i.e., z = 1 (mod 6) or z = 5 (mod 6). Now suppose there are only finitely many primes congruent to 5 modulo 6, say p_1, ...,…

Descriptive statistics I can describe the data with the help of descriptive statistics. The data can be described with the help of various types of graphs and central tendency. Measures of central tendency are mean, median and mode. Mean is reliable for normal data. Median is reliable for a data which has outliers. And mode is preferred when data is categorical. There are various types of graphs like pie chart, bar graph which gives us a pictorial representation of data. Measure of…

that incorporated portions of NCRP Report no. 116 as well as emergency planning, assessment of radiation exposure and training. NCRP reports were critical in the 2002 revision to skin dose, 1999 guidance on prenatal expose, 1996 guidance for risk for occupational exposure and 2010 guidance on measuring effective dose equivalents. (Kase, 2016)(Jones, 2005) The Environmental Protection Agency has utilized NCRP recommendation for the major policy decisions. The 1960 Federal Guidance for…

In discussion question 1 I discussed carpal tunnel. Treat carpal tunnel syndrome as early as possible after symptoms start. Take more frequent breaks to rest your hands. Avoid activities that worsen symptoms and applying cold packs to reduce swelling also may help. Other treatment options include wrist splinting, medications and surgery. As you go through your day, keep an eye on how tense your hands are and how much pressure you put on them. If you can back off even a little, your hands and…

Carpal Tunnel Syndrome is a condition in which the space within the carpal tunnel in your wrist is reduced and the median nerve, one of the major nerves in your hand, is pinched as it travels through the tunnel. Injury, fractures, rheumatoid arthritis, work stress, repetitive use of hand tools, and things such as factory work, gardening, or typing over a long period of time, are typical causes of Carpal Tunnel Syndrome. If your job makes your carpal tunnel worse, doctors often recommend a…
