Activity 3: Yeast Fermentation of Different Carbohydrates? Experiments test the predictions made by a hypothesis. The hypothesis should be stated very clearly and unambiguously. If the results of the experiment were predicted by the hypothesis, the results support the hypothesis (NOT “prove the hypothesis is true"). If the results are different than those predicted by the hypothesis, then the hypothesis is retested, modified or discarded. Many times an experiment is actually testing the Null Hypothesis. The null hypothesis states that...

PLEASE help ??
A researcher conducted a single sample t-test on results of an experiment with n = 18 participants and the computed t = -2.28. What is the correct conclusion from this experiment if p < 0.05, 2-tails test is used for hypothesis testing? O A. The researcher failed to reject the null hypothesis and concluded that there is a significant treatment effect. O B. The researcher rejected the null hypothesis and concluded that there is a significant treatment...

Question:
The Australian Government’s Energy Efficiency Opportunities
program encourages large energy using businesses to improve their
energy efficiency. It does this by requiring businesses to
identify, evaluate and report publicly on cost effective energy
savings opportunities. As part of the process of identifying
factors impacting on electricity consumption, a large super market
chain took a sample of 30 stores and investigated the relationship
between electricity consumption and store size....
