RNA world hypothesis

with the probability set at 0.05, the chi-square was bigger than the critical value. This data rejects the null hypothesis which states that there will be no significant difference between the observed and expected portions of birds at the feeding stations. So, rejecting the null hypothesis that there is no difference in the observed and the expected in favor of the alternative hypothesis that there is a significant difference . The three species that…

a web-based research software that provides survey platforms. These results were input into SPSS so that statistical analysis could be performed. Given the nature of the variables of interest (continuous), two correlations tests were performed. Hypothesis One: Correlations Test A sample of n = 63 subjects was obtained with scores on Communication Apprehension (M = 3.00, SD = 1.54) and Academic Performance (M = 2.13, SD = .96). It was hypothesized that Communication Apprehension would correlate…

by many parties involved. However, research examining parents’ attitudes toward food advertising is limited. Due to there being limited data available, the authors give reason as to the purpose of the research adequately. Bakir and Vital’s null hypothesis is “Parents’ attitude toward food advertising will be positively related to their ethical judgments of the food advertising targeted at children” and they state nine alternative hypotheses (2009). Methodology is broken up into a few sections,…

relationship between immigration and the economy. We want to calculate the mean of the values and get an overall estimate to show the difference between the estimated treatment as well as the sum between the groups to say if our hypothesis is correct or if our hypothesis is false. The two-way ANOVA testes were broken up in to six tables to produce accurate data information. The tested data as is follows in the following…

more effective for preventing getting the flu: the shot or nasal spray. What were the null and alternative hypotheses? Null Hypothesis: The shot is more effective than the nasal spray. Alternative Hypothesis: The shot is not as effective as the nasal spray. Were the results of this test statistically significant? .08>.05 Which means the results are not significant. The hypothesis will be accepted. Was the sample appropriate for this study? The test is appropriate. Discuss how you would…

What hypothesis is being tested? hypotheses: first, students who report LD or ADHD would be victimized more frequently compared with students who do not report LD/ADHD diagnoses; second, students with less secure attachment styles to parents would experience more victimization compared with students with better attachment to parents; third, students with insecure attachment style to teachers would experience more frequent victimization compared with students with more secure attachment to…

The purpose of this study was to determine the presence of the social stigma of loneliness and how it presents itself in different races, which in this case included both White and Hispanic. This study used the two independent variables of race and loneliness state in order to create several characters, which were then presented to the participant. Race was operationalized by changing the name of the character to represent either a White or Hispanic person. Some examples of the names used…

sexual attraction. They hypothesized that males who come across an attractive female while experiencing a strong emotion such as fear will find the female more attractive than by males not experiencing a strong emotion, which is also the alternative hypothesis. The independent variable is a strong emotion such as fear. This was operationalized by participants being on an unsteady bridge that would tilt and sway causing a fear of falling. The bridge had very low handrails made of cable and was…

the benchmark of .05 means the data from the lab was significant and statistically rejects the null hypothesis that there was no correlation between residency and aggression between male crickets. The null hypothesis suggested the wins should have been equal at 239 wins for the intruder and 239 wins for the resident. If the chi squared test resulted in a p-value above .05 then the null hypothesis would have been accepted and could confirm no relationship between residency and aggression.…

available in the Campus Lake? Population Ecology Experiment Null Hypothesis: The presence of Blue-Green Algae will not have an effect on the Chlamydomonas population. Alternative Hypothesis: The presence of Blue-Green Algae will have an effect on the Chlamydomonas population. Community Ecology Experiment Null Hypothesis: Nitrate concentration will not have an effect on chlorophyll levels in the Campus Lake. Alternative Hypothesis: Nitrate concentration will have an effect on chlorophyll…
