Create a null hypothesis for the following research questions:
a. What are the differences between emergency room shifts on medication errors?
b. On a clinical trial of a new drug, what will be the effects over a currently used drug?
test
a. The null hypothesis for the research question "What are the differences between emergency room shifts on medication errors?" can be formulated as follows:
"The emergency room shifts do not have any significant differences in the occurrence of medication errors."
To determine the null hypothesis, we essentially assume that there are no differences between the shifts concerning medication errors. Later, through data analysis, we will either reject or fail to reject this assumption based on the evidence collected.
b. The null hypothesis for the research question "On a clinical trial of a new drug, what will be the effects over a currently used drug?" can be stated as follows:
"There are no significant differences between the effects of the new drug and the currently used drug."
In this case, the null hypothesis assumes that the new drug has no impact or difference compared to the current drug being used. The purpose of the study would be to gather data to either support this null hypothesis or reject it based on evidence and analysis.
