Retrieved January 31, 2017. The basic concept that is being explored are about enzymes. Enzymes are proteins that are known for being sparkplugs in a chemical reaction. Enzymes have a shape and for them to ‘spark’ they must have the proper substrate for it to work U. This does not change the enzyme’s…

The Alternative Hypothesis (H1): People who take the Drug_2 sleep equal or more than taking the first soporific drug. Descriptive Statistics 1. Histogram A histogram is one typical visualization representation of the distribution of numerical data, which offers a good…

chose to use was the one-way ANOVA test. The one-way ANOVA test was chosen because it is used to measure the mean difference between the groups. For the one-way ANOVA test we have a null hypothesis that all groups would have an equal mean. After doing the one-way ANOVA test we expect that we reject the null hypothesis and that the group that received money under happy circumstances is the group that has the mean that is the most lavish and the group that received the money under negative…

than 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.…

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…

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…

which vaccine is 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…

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…

final trial of 20ºC water results are listed in table 1. The range for the 20ºC water was a difference of 3 lines and the mean was 26.3 lines also shown in table 1. The standard deviation for 20ºC water was 2.08. The t-test concludes that the null hypothesis is false. With respect to the entire class, conclusively the range of the entire group’s data was 22 in 5ºC and 68 in 20ºC. The average number of lines crossed for the entire group in 5ºC water was 5.36 lines and in 20ºC was 43 lines both…

Introduction: The null hypothesis was that there is no difference in dissolved oxygen and primary production with depth, the dissolved oxygen amounts will be constant with differences in depth. The alternative hypothesis is that there is a difference in dissolved oxygen and primary production with depth, the dissolved oxygen amounts will decrease as depth increases. Methods: Water samples were incubated in light/dark bottles with no air bubbles in the bottles. DO concentrations…
