Hypothesis Testing

8. Draw conclusions – Assuming that your experiment produced results identical to those seen in Table 4, would you reject or accept the hypothesis that you produced in question 3? Explain how you determined this.

An experiment could be devised in which bats are taken in a large quantity and one

Hypothesis testing and development provides a baseline for taking ideas or theories that were initially created by another person in regards to the markets, economy, or investing and then determining if the

Hypothesis is typically used in quantitative research only. Moreover, when a question poses an inquiry on the relationship between two variables, a hypothesis is a statement declarative in nature of the relationship between different variables (Pajares 2007). A researcher chooses whether to use a question or a hypothesis depending on the purpose of the research, its objectives, the methodology for the research and the preference of the audience to receive the research. A researcher must be able to interpret the final outcome with reference to the research questions or the hypothesis used (Pajares 2007). A research requires a minimum of two hypotheses namely a null and an alternative hypothesis.

Select one (1) project from your working or educational environment that you would use the hypothesis test technique. Next, propose the hypothesis structure (e.g., the null hypothesis, data collection process, confidence interval, test statistics, reject or not reject the decision, etc.) for the business process of the selected project. Provide a rationale for your response.

hypothesis is rejected (Salkind, 2014). The critical value is also used to calculate the margin of error (Salkind, 2014). Lastly, the critical value is determined from the alpha or significance value of the hypothesis test (Salkind, 2014).

Hypothesis- Ice cream melts faster in warm weather vs cold weather. Null Hypothesis- weather has no bearing on ice cream melting.

In an experimental research, the use of a research question answers the thesis statement that enables one to research about a problem (Yin, 2013). From the experiment, the research question can be clearly stated as “which vaccine is more effective for preventing getting the flu”. In this case, the problem being researched about is the flu the possible solutions to this problem which the use of vaccines is being analyzed. The null hypothesis of this experiment states that there is no effective vaccine for preventing getting the flu while the alternative hypothesis states that there is an effective vaccine for preventing getting the flu.

Null hypothesis. The null hypothesis, denoted by H0, is usually the hypothesis that sample observations result purely from chance. In this case, according to null hypothesis there is no significant difference between business students at Rocky University who were involved in cheating and business students elsewhere.

There is a null hypothesis and an alternative hypothesis. The null hypothesis usually states there is no difference and an alternative hypothesis states there is. A result is positive if it rejects the null hypothesis. A result is negative if it does not reject the null

“Hypothesis testing is a decision-making process for evaluating claims about a population” (Bluman, 2013, p. 398). This process is used to determine if you will accept or reject the hypothesis. The claim is that the bottles contain less than 16 ounces. The null hypothesis is the soda bottles contain 16 ounces. The alternative hypothesis is the bottles contain less than 16 ounces. The significance level will be 0.05. The test method to be used is a t-score. The test statistic is calculated to be -11.24666539 and the P-value is 1.0.  The P-value is the probability of observing a sample statistic as extreme as the test statistic, assuming the null hypothesis is true. The T Crit value is 1.69912702. The calculations show there is enough evidence to support the claim that the soda bottles do

(14.87*16/0.550329055/5.4772 = 0.1005) So, we have p = 0.1005. Then we ask if p is greater than a (alpha). Since p is greater than a = 0.10 we decide that there is significant evidence supporting the claim to not reject the Ho. So, we accept the null hypothesis that on average there is less than the advertised 16oz in each bottle.

The research methodology is to divide the teams by their salary means. Then the win means will be compared to determine if there’s a significant difference in production of high salary teams and lower salary teams. 1, teams with larger payrolls, will be defined as teams with payrolls that are average or above average (see chart team A) and 2, teams with smaller payrolls, will be defined as teams with less than average payrolls (see chart team B).

The null hypothesis suggests that there is no difference between the means of the three samples, while the claim in the alternative hypothesis suggests that at least one mean is different.

For every statistical experiment, an alternative hypothesis and a null hypothesis is constructed. If "the variance between groups exceeds what is expected in terms of the variance" the null has been disproven and the independent variable is shown to have had a measurable influence upon the experimental population (Analysis of variance. 2012, Stat Primer). In statistical experimentation, the hypothesis (which the experimenter actually thinks or hopes will occur) is never technically proven; rather the null hypothesis is refuted. The actual hypothesis of the experimenter is 'guilty until proven innocent' (What is a null hypothesis, 2012, Null Hypothesis).
