Question No 3. Tests Using Contingency Tables:

A researcher selected sample of customs from 4 companies and asked them if the companies care give warranty on sold items or not. Assume observed values from your own (fill the below table by assuming any values of your choice) and test the claim that the proportion of customers of each company who got warranty is the same for each company by choosing alpha of your own choice. (Marks 2.5)

	Company A	Company B	Company C	Company D
Warranty: Yes		86	56	73
Warranty: No		25	31	26

A researcher tests a new drug on a sample of known schizophrenic patients, hypothesizing it will reduce their symptoms. After the drug trial their symptom scores are assessed (higher scores = more disordered, lower scores = more healthy). This score is converted into a z score of -2.11. The researcher used an alpha of .05. a. What is the p-value for this study? b. What do you conclude from this test? c. What does the p value mean or what...
