Researchers were investigating whether there is a significant difference between two medications, R and S, designed to reduce fl
eas found on cats. From a sample of 300 cat owners, the researchers randomly assigned 150 cat owners to use medication R on their cats and the remaining cat owners to use medication S. For the cats using medication R, 88 percent had no fleas. For the cats using medication S, 90 percent had no fleas. Which of the following is the most appropriate method for analyzing the results? A two-sample z -test for a difference in population proportions
A two-sample z-test for a difference in sample proportions
A one-sample z-test for a sample proportion
A one-sample z-test for a population proportion
A one-sample z-test for a difference in sample proportions
A) A two-sample z -test for a difference in population proportions
Step-by-step explanation:
To determine whether a difference in proportions is significant, the two-sample z-test for a difference in population proportions is the most appropriate method for the analysis.
It would be $390 for the 4 hours and the cleaning fees. And the slope would be -13 if you are going from 12 to 7 but would be 13 if you are going from 7 to 12...
