Solve the problem.
A drug company developed a honey-based liquid medicine designed to
calm a child's cough at night. To test the drug, 105 children who
were ill with an upper respiratory tract infection were randomly
selected to participate in a clinical trial. The children were
randomly divided into three groups - one group was given a dosage
of the honey drug, the second was given a dosage of liquid DM (an
over-the-counter cough medicine), and the third (control group)
received a liquid placebo (no dosage at all). After administering
the medicine to their coughing child, parents rated their
children's cough diagnosis as either better or worse. The results
are shown in the table below:
Diagnosis |
In order to determine whether the treatment group is independent of
the coughing diagnosis, a two-way chi-square test was
conducted.
1. State the alternative and the null hypothesis.
2. Calculate test statistic
3. Determine the chi square critical value.
4.Write the decision rule
5. Decision and Conclusion
Given table data is as below
calculation formula for E table matrix
expected frequencies calculated by applying E - table matrix formulae
calculate chisquare test statistic using given observed frequencies, calculated expected frequencies from above
------------------------------------------------------------------ |
we have enough evidence to support the claim that whether the treatment group is independent of the coughing diagnosis,

Using the book, write another paragraph or two: write 170 words: Q: Compare the assumptions of physician-centered and collaborative communication. How is the caregiver’s role different in each model? How is the patient’s role different? Answer: Physical-centered communication involves the specialists taking control of the conversation. They decide on the topics of discussion and when to end the process. The patient responds to the issues raised by the caregiver and acts accordingly. On the other hand, Collaborative communication involves a...
