14. Cindy is attempting to stop her dog from incessant barking by using a collar that emits
an unpleasant scent when the dog barks. Since she has recently taken a research course
so she decides to approach the situation from a scientific perspective. She measures the
number of times Scruffy barks from 8 to 9 pmfor 3 nights. On the 4 th night she uses the
dog collar and begins collecting data. Over the course of the next 5 nights Scruffy
completely stops his inappropriate barking. Cindy then removes the collar and continues
to monitor Scruffy from 8 to 9 pm for another week.

18. Martha is trying to figure out what type of exercise will help her lose the most weight.
She decides to spend the summer figuring it out. She weighs herself and begins walking
on a treadmill for 30 minutes 6 days per week at 2.8-3 miles per hour. She plans to use
this method for 4 weeks. After the end of 4 weeks, she weighs herself and found that
she has lost 6 pounds.

30 minutes 6 days per week. She plans to ride 3 miles each day. After the 4 weeks
Martha finds that she has lost a total of 11 pounds.
For the last 4 weeks Martha decides to take an aerobics class 3 times per week. The
classes are 1 hour in length. At the end of that 4- week period she finds that she has lost
a total of 20 pounds.
