The unit rate is 10:1 because unit rates are out of 1
You would find that by dividing 20 and 2 by the same number to get to one for this specific problem. 20 divided by two is ten and two divided by two is one. So that is your answer for part b. I can’t draw a graph however so sorry
Answer: d. There is no relationship between education level and smoking habits.
Step-by-step explanation:
The null hypothesis is the affirmation that two parameters or phenomena do not have a relation between them.
