(Guili Zhang‚ 2009) For the first group our hypotheses are going to be: H0: Null hypothesis: There is no significant difference between the learning gains after using simulation only and after using the whole system. H1: Alternative hypothesis: There is a significant difference between the learning gains after using simulation only and after using the whole

the two groups. The null hypothesis should be rejected because the P-Value is 0.005 which would mean that the groups are different. 2. State the null hypothesis for the Baird and Sands (2004) study that focuses on the effect of the GI with PMR treatment on patients’ mobility level. Should the null hypothesis be rejected for the difference between the two groups in change in mobility scores over 12 weeks? Provide a rationale for your answer. Answer The null hypothesis would be that the means

Develop a Research Question to Compare a Single Sample Mean to a Known or Hypothesized Population Mean: In your area of psychology‚ formulate a research question that can be addressed using a one sample t-test. State your null hypothesis‚ your alternative hypothesis‚ and your known or hypothesized population mean.

the basil seed‚ would affect the growth. The null hypothesis for this experiment was that there would be no statistical difference between the green‚ yellow‚ and red basil seeds’ growth. Three alternate hypotheses are: If we expose the green seed to 48 hours of sunlight and the yellow seed to 24 hours of sunlight‚ then the green seed with grow more than the yellow. The opposite of this hypothesis would alternate 2. Another alternate hypothesis is (3): if we expose the yellow basil seed to 24 hours

You will use the data you gathered above for the problems below and more question in future weeks. Practice Problems: 1) Use your data from above. This week assume that historically the average person takes 3 vitamins on a daily basis. Conduct a hypothesis test analysis to determine if 3 is still the correct average number. Write your hypotheses in correct statistical notation. Finally use the important numbers from your output to explain your results. Use alpha = 0.05. Post only the relevant

interact with lactose compared to maltose. In unit 7.4 the experiment tested the role‚ if any‚ that metal ions have on the activity of lactase. My hypothesis for unit 7.3 was knowing that lactase is specific for lactose‚ lactose will separate into galactose and glucose‚ as maltose will not change (153-155). Lactase should like lactose. For unit 7.4 my hypothesis was that EDTA will remove the ions‚ and will not work. Materials/Methods For unit 7.3 the experiment needed 2 microfuge tubes one labeled

The first Hypothesis statement is; there is a difference in the coffee consumption rate of Americans based on gender. The second Hypothesis statement is; there is not a difference in the coffee consumption rate of Americans based on gender. The team will use the Confidence Interval to check if there is no significant difference
