3. Is Albany colder than Altlanta? 100 randomly selected days in winter were analyzed for each city and compared In the above scenario, we should be using a (Hypothesis Test or Confidence Interval) procedure, it is using (Proportions or Means) and it has (1 or 2) populations

4. Do dog owners prefer the outdoors more than cat owners? 100 dog owners and 100 cat owners were asked if they prefer to be inside or outside. In the above scenario, we should be using a (Hypothesis Test or Confidence Interval) procedure, it is using (Proportions or Means) and it has (1 or 2) populations

5. Charmin wishes to estimate the difference between the number of rolls of toilet paper people in Los Angeles county have to how many those in Ventura county have. To find out, the company asks several households in each county how many they have currently in their house. In the above scenario, we should be using a (Hypothesis Test or Confidence Interval) procedure, it is using (Proportions or Means) and it has (1 or 2) populations
