Hypothesis testing

According to Mrs. Doe’s observations and ratings, Bob obtained an Adaptive Behavior Composite which fell in the Normal range for his age. Bob’s Communication domain score of 100 on the parent rating fell in the Normal range for his age. Parent ratings suggest a personal weakness in expressive communication. Bob’s Receptive domain and Written domain fell within the Moderate High range. Daily Living Skills domain score was not obtained due to subtest selection. Bob’s Activity of daily living fell…

Paper Summary: “Geographic Variation in the Acoustic Traits of Greater Horseshoe Bats” (Keping Sun et al.) Introduction This experiment focused on understanding the process of the diversification of phenotypic traits between populations of individual species due to geographic distance or isolation between each population. These researchers aimed to analyze the microevolutionary processes of genetic drift, cultural drift, and adaptation as factors that could have driven geographic variation in…

This result is upheld by the perception that few scarps don't proceed from the Nullarbor Plain toward the ca. 2 Ma (James et al. 2006) Roe Plain surface. Two traced scarp cause displacement of the Roe Plain surface vertically by about 5 m individually as show in figure 7b and seem to connect into one scarp when traced towards the Nullarbor Plain margin. Estimated vertical slip rate in the order of 2.5 m/Ma is acquired, or two times that number supposed that it is accepted that the scarps join…

polynomial P in Z[x] of positive degree such that the values P(0), P(1), ... are all prime. Proof: Suppose otherwise, so P(0) = p for some prime p. Then the constant term of P is p, so p | P(kp) for k >= 1 an integer. Since these values are prime by hypothesis, P(kp) = p for k >= 1. Thus the polynomial P(x) - p has infinitely many roots over the field R (the real numbers), a…

impact of variability of foreign exchange gains and losses on ROE. These tests yielded a P-Value of 0.04 or 4%. A P-value of 4% is less than set significance levels at 5% (95% level of confidence) and 10% (90% level of confidence) hence the Null Hypothesis which states that there is no significant impact of foreign exchange gains and losses on the profitability of Oil and GAS Companies cannot be rejected. This implies that there is a significant impact of foreign exchange gains and losses on the…

Reflection essay #4 Our discussion about relationship between creativity and spatial reasoning reminds me of a study of “Mozart effect” (Rauscher et al. 1993), which showing that music by Mozart can temporary improves experimental subjects’ spatial reasoning ability comparing to the control group. Of course, the study is not promoting Mozart’s work. Some recent work shows that the music with seizure frequencies close to the working frequencies of brain can help with stimulating brain activity.…

The Infinity POM By: Vinayak Prathikanti, Varun Popli, & Alan Xiao For the second month, we had the Infinity POM, and it definitely made us think a little. The problem said to consider all of the infinite numbers between 0 and 1, then all of the numbers on the number line. Which one of these is the larger infinity? Now before we say anything else, we want to tell you that this is an extremely open ended problem, and that it is very hard to argue one side. While this is true, we…

Measuring of Execution after training: Table No. 1: Details of respondents’ analysis towards measuring of execution after training. Measuring of Execution after training Frequency Percent Valid Percent Cumulative Percent Valid 50% 161 33.3 33.3 33.3 25% 322 66.7 66.7 100.0 Total 483 100.0 100.0 Source: Field Survey INTERPRETATION: The above table no. 1 attempts to conclude that, 33.3% of the respondents opined with regard to measuring of evaluation after training program that 50% of the…

Results In the univariate analysis factors race and side proved to be insignificant by the Wald test at 5% significance level. Hence the eruption sequence does not significantly differ among the Races and remains unchanged between left and right side in the mouth. Then a multivariate CoxPH model was fitted using variables District, SS, gender, jaw and type which were the significant variables in the univariate analysis. These five variables continued to be significant in the fitted multivariable…

Q1) What type of reinforcement schedule does random drug testing represent? Is this type of schedule typically effective or ineffective? The type of reinforcement schedule that random drug testing represents is the Variable-Interval(VI) schedule of reinforcement. In Variable Interval schedule a response is rewarded after an unpredictable amount of time has passed. This type of schedule is done randomly and is unexpected. The word random used in this case itself represents the schedule. Variable…
