According to table 2, body postures show significant differences in working stages (P=0.2) The most important and striking difference is related to body`s neutral position. The results show that body`s neutral position makes up 61.7% workers` working time. Body`s neutral position accounts for 57% of body posture in foundation, 55% in carcass, and 63.8 % in finishing stage. In other words, most body`s neutral positions were observed in foundation. Gentle bending posture was reported 21.2%. This…

Statistics Worksheet Part A Question 1 a) Below is the calculation for the Pearson product-moment correlation coefficient between the total number of problems correct and the attitude toward test taking. Total no. of problems correct (out of a possible 20): X Attitude toward test taking (out of a possible 100): Y (X - X ̅)² (Y - Y ̅)² (X-X ̅)(Y-Y ̅) 1 17 94 1.96 204.49 20.02 2 13 73 6.76 44.89 17.42 3 12 59 12.96 428.49 74.52 4 15 80 0.36 0.09 -0.18 5 16 93 0.16 176.89 5.32 6 14 85 2.56 28.09…

/* 1 */ - This variable is equal to a constructor function called Winston. A constructor function is a function that is called everytime a new instance of this variable is created The parameters of this specific function are nickname, age, x, and y. /* 2 */ - In this line, this. refers to the current object instance which in this case is nickname. It is basically saying that the nickname property of this is equal to whatever is passed in the constructor function itself. This object is…

Seatwork: A. Convert the following rotation to degrees and revolution. 1. 1/3 rotation : counterclockwise 2. 4/5 rotation : clockwise 3. 13/3 rotation clockwise B. Change each radian measure to degree measure and sketch the angles in standard position. 1. / 3 rad 2. -3 / 4 C. Determine which of the following angles are quadrantal angles. 1. 850 = __________________ 3. 5600 = ___________________ 2. 2700 =…

The first opposing article does not provide significant evidence that preworkout supplementation is safe, and can therefore be interpreted as inconclusive. The authors did not provide a specific hypothesis. In this study, researchers conducted two separate trials to determine the safety and effectiveness of a PWS on healthy men and women. The first part of the trial was meant to specifically research the safety of using PWS. The second trial took a closer look at the actual impact preworkout…

The Situation You have five bales of hay. For some reason, instead of being weighed individually, they were weighed in all possible combinations of two: bales 1 and 2, bales 1 and 3, bales 1 and 4, bales 1 and 5, bales 2 and 3, bales 2 and 4, and so on. The weights of each of these combinations were written down and arranged in numerical order, without keeping track of which weight matched which pair of bales. The weights in kilograms were 80, 82,83, 84, 85, 86, 87, 88, 90, and 91. Your Task…

2.2 The method At the searcher will do the searching process as follows: I. Start at the origin and search the cell number 1 and then number 2, 3. Now, the first revolution is completed. If the target not found, then go to step II. II. Since, the target is not detected, then the searcher will do the second revolution which contain the cells number 4 to number 14 as in Fig.1(a). And so on until the hole will detect. Assuming that the target is randomly located in the space at the…

From the percent difference I can conclude that neither surface area, surface texture, nor mass of block has that big of an impacted on the friction. The higher the percent difference is the more effect friction would have on it, with the lower percent difference says it wouldn’t affect friction. For surface area testing side A against side B on smooth sliding for percent difference was60.78%, over half (50%) but not by much. For weight off sandpaper the difference was only 40.00%, where on…

My average adjacent length was about 4.5% less than the correct length, so it concludes that the illusion had a small impact on my perception of line. 2A: How is this illusion related to depth perception? When we see the two lines to be at different distance, our brain try to figure out that which is near to our vision by showing the visible distance. So the line which form near edge of an exterior corner, we think that this line looks shorter…

Jones and Holmgren (2007) presented a biomarker-adaptive parallel two-stage design to evaluate a treatment that it is thought to have different response in different subgroups defined by a prespecified biomarker positive versus negative. The idea is to run two parallel two-stage designs, one in each of the groups (biomarker-positive and biomarker-negative), and then to run an adaptive parallel design. Thus, the design begins with two parallel studies, one conducted in $N_{1}^{-}$…
