Statistical hypothesis testing

Similarity indices and genetic distance The overall mean similarity index for Brassica oleracea accessions calculated based on all AFLP fragments amplified using Nei’s (1978) similarity index, ranged from 0.297 to 0.999 with an average of 0.744 (Table 3). The highest similarity indices (0.999) and the lowest genetic distance (0.001) were between the accessions of the same crop variety and geographical region, e.g. spring cabbage HRIGRU4564 and HRIGRU4571 from Cork. Accessions having close…

The experiment consisted of numerous limitations and uncontrolled variables which impacted on the validity of the outcome. The lack of repetition was a major limitation in this experiment. The shortage of repetition forbids the elimination of outliers that may cause inaccuracy in the practical outcome. The lack of repetition in this experiment provided erroneous practical results where experimenters are mislead due to outliers, hence conclusions could not be accurately drawn. According to…

Introduction Conformity assessment is generally any activity undertaken to determine, whether a product, process, system, person or body meets relevant standards and fulfills specified requirements [1]. The main application of conformity assessment is in facilitating trade. In a particular kind of conformity assessment, sometimes called inspection, the determination that a product fulfils a specified requirement relies on measurement as a principal source of information [2]. In each quantified…

In the Red Bead Experiment, a small proportion of red beads are interspersed with white beads. In this model, the white beads are desirable by the customer whereas the red beads are not and can be considered as errors. The employee receives instructions on how to collect the beads properly and proceeds to do so. The results are then tallied documenting the number of errors (red beads) which are identified. There are a number of interpretations of the data derived from this experiment…

Results Pearson-R Correlation The data underwent correlational analysis using the Pearson-R coefficient and obtained the following results: Table 1. N E O A C SPS Pearson Correlation .562** -.273** .022 -.294** -.218** Sig. (2-tailed) .000 .000 .676 .000 .000 N 372 372 372 372 372 ** Correlation is significant at the 0.01level (2-tailed) Based on the table above, the independent variables N (.562), E (-.273), A (-.294), and C (-.218) are significantly correlated to the dependent variable,…

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…

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…

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…

In this project, I will analyze the problem of gender inequality in terms of labor income. This problem is important in our society because people with same background and same experience should be treated the same in the same working environment. Women should not be judged based on their biological gender. The data sample used in this project is working individuals between ages 25 and 54 from Current Population Survey, 2012. Sample size contains 999 observations. I will first discuss the…
