Hypothesis testing is used to state a claim based on a parameter and test the stated theory (Vasilopoulos, 2011). Crounse Corporation is considering making annual physicals mandatory for all employees. The company hypothesizes that employees who receive annual physicals will incur lower medical costs. A one-sample hypothesis test could be used to prove or disprove the company’s theory. A null hypothesis shows no relationship between two groups (Mirabella, 2011). In the case of annual physicals,…

versions of the null hypothesis? The three versions of the null hypothesis are: (1) “the observed difference was created by sampling error”, (2) “there is no true difference between the two groups” and (3) “the true difference between the two groups is zero.” (Barker, 56-57) 2. Is the null hypothesis typically stated in social scientific research? Why/why not? The null hypothesis is not usually stated in social scientific research. Researchers rarely state the null hypothesis in their academic…

Soil preference of the Red Compost Worms, Eisenia fetida INTRODUCTION Earthworms provide countless benefits to humans, plants and animals, by improving drainage, advancing nutrient accessibility, and providing a steady soil system, helping to develop farm production. They benefit the soil ecosystem by decomposing and recycling organic matter, opening up pores inside the soil to develop its formation and supplying food for predators . By adding nutrients to the soil they inhabit, earthworms are…

conditions, indicating there was no relationship between these two conditions. This means we need to accept the null hypothesis that there is no interaction between these two sets of conditions. It should be noted that even if we adopted a two-tail hypothesis, that the result would still be insignificant, however not by large degree (P=0.104). Previous research made a one directional hypothesis seem more appropriate, due to previous research showing visuospatial bootstrapping to be a robust…

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…

in metaphorical language use of the experimental group and the control group at the beginning of the metaphor awareness treatment, an independent samples t-test was conducted for the data gathered from the participants’ recent writing test. The statistical analysis indicated that there was not a significant difference in the metaphorical language use of experiment group (M = 1.59; SD = .70) and control (M = 1.44; SD = 1.00); t (43) = .58, p = .56. Levene’s test for equality of variances was…

dependent variable is the subjects Calorie/menu choices. The researcher has posed three Research Question, and has identified a null and alternative hypothesis for each. RQ1: Are young Millennials’ menu choices on low-Calories items correlated with different menu designs applying menu psychology? Tian has created a null hypothesis and alternate hypothesis for each factor studied when considering the menu design to include the serial position effect, the gaze motion theory and the salience…

level of confidence from Salkind’s chart. Based on these results, the null hypothesis is rejected for these tests. This along with higher mean averages for ADHD children suggests that the ADHD children did indeed outperform their non-ADHD classmates. The evidence showing no difference in performance on some tests (above) and ADHD children outperforming their peers on others, contradicts Colombo-Dougovito’s research hypothesis that children with ADHD are less physically fit than those without…

A case study reflecting on observations of children’s schematic interests. In the paper I will be discussing the history and theories of schemas. I will include observations on a child’s schematic interests and my role as the practitioner. A Schema is a pattern of repeatable behaviour into which experiences are assimilated and that are gradually coordinated. (Athey, 1990:37) Children’s patterns are influenced through their genetically pre-determined biological development and the socio-cultural…
