Explanation / Answer
1. Strongly correlated:
(i) X = time spent on running on a treadmill. Y = calories we will burn. The more time we spend running on a treadmill, the more calories we burn.
(ii) X = length the hair grows. Y = quatity of shampoo needed. The longer the hair grows, the more quantity of shampoo we need for cleaning.
2. Uncorrelated: X = height of a person . Y = number of softdrinks he takes per day. There is no correlation between the height of a person nd the number of softdrinks he takes per day.
3. (i) X = number of hours spent on studying per day. Y = Final score student gets. The more a sudent spends on studies, the more will be his final score.
(ii) X = time spent on marketing a product. Y = number of customers. The more time er spend on marketing a product, more will be the number of customers
4. (i) X = number of days absent. Y = final score of the student.
The more number of days the student is absent, the less will be his final score.
(ii) X = speed of a car . Y = time to reach destination. The more speed of the car, the less will be time to reach destination.
5. X = number of hours of study per day. Y = marks I get in examination. This will help me in estimating the time of my study per day for desired increase in my mark in the examnation
