Hypothesis testing

According to Figure 1, the tactile stimulus was the fastest reaction followed by auditory and visual. The tactile stimulus was the fastest reaction because it is the reaction in which the nerve takes the lowest amount of time since it only sends the message to the brain and then back down to your muscles. The tactile stimulus is more of a reflex, it is not like the visual stimulus where the brain has to think of the purpose before closing the hand. For both person one and two the tactile…

s: Translations are the process of moving around all of the coordinates that make up a shape. All the points move the same distance in the same direction. The transformation is isometric which means that it does not change in shape or sides. If the pre-image moves either right or up the coordination would be adding. If the pre-image moves either left or down the image would be subtraction. The picture to the right is an example of translation. The answer to the question at the bottom would be…

In the current study, we developed and evaluated scales to measure HAPA concepts regarding physical activity among diabetic patients. Psychometric testing in this study provides preliminary evidence that the HAPA scales are valid and reliable measures for variables of this model. Both factor analysis and structural equation modeling confirmed the construct validity of the scales. Nevertheless, further research is required to address some overlaps between the belief measures. It is evident that a…

One result of random genetic drift and gene substitution is mutant alleles, however the probability that these mutations become fixed in a population is not solely dependent on the advantageous nature of the allele, rather the probability of fixation is determined by the allele frequency, the selective advantage or disadvantage, and the effective population size. The probability of fixation for a particular allele is demonstrated by the equation where probability is equal to 1 minus the…

The percentage of uncertainty evaluates my data by showing how accurate my results are. The Sarsons and Pickling vinegar I titrated were extremely accurate as there was 0.04% and 0.05%of uncertainty, whereas the ASDA vinegar I titrated was 0.20% uncertainty; this was the highest percentage of uncertainty which shows that this vinegar is the most unreliable in order to compare to the results of the market stall vinegar titration. Conclusion: In conclusion trading standards believe that the…

CS2301 df5 Questions: Using Figure 17.5 from the textbook explain why we have a “big mess” of our free space memory allocation Answer: Below figure show one example of putting the memory. Quoted: ARPACI-DUSSEAU. R., ARPACI-DUSSEAU, A. (2012, ch17-8) In above example, assume total size is 4096, header eat 16k, each chunk total eat 108k (100 + 4 k header + 4 k chunk). In theory (assume perfect allocation), no waste space resulted. Then total 37 chunk block (108k) can be fitted. However, the…

More than 65% of ovules were just enlarged without undergoing callus or shoot phase independent of the sucrose concentration. Rest of the ovules was either with no development or dead after 8 weeks of culture period. The effect of sucrose concentration on ovule response was not pronounced (Table 18). When comparing the suitability of sucrose concentrations (2% or 4%, 4% 0r 6%, 2% or 6%) for ovule culture depending on the genotype, there is no significant difference for both genotypes on whatever…

was inside the black bottle was to understand the basic elements of the scientific inquiry process. We hypothesized that there was a push pin and string inside the unknown bottle—this was based on observations. In order to determine whether our hypothesis was correct or not, we massed out the unknown bottle, an empty bottle, and items that could potentially be inside the bottle. We also put items inside the empty bottle and compared the sound to the unknown bottle. The results showed that there…

However since we have the four variables and that we’re measuring first year average scores. The formula should look like this: First year average score (%) = β0 + β1non-academic member + β2satis first-year + β3math-center + u Since first year average score is a percentage variable, it is often used in the level form as a result. So models with level-level or level-log will work best with this average score for estimating. However since we are measuring with more than two variables,…

ceteris paribus, 1% increase in inflation rate is correlated with 2.57% increase in infant mortality rate. While this finding consistent with our belief, the high p-value indicates that even at 10% level of significance we fail to reject the null hypothesis that inflation rate has no significant influence on infant mortality rates. The estimated coefficient of health expenditure 0.1626, denoting that, ceteris paribus, for 1% increase in healthcare expenditure, infant mortality will do up by…
