Q4 As a factory manager, you are concem about the health of your workers. In this regard, you have randomly sampled 15 staffs of your factory and recorded down their water consumption under different working temperatures. In particular. when they have already spent three hours under the working temperature. The collected data are shown in Table Q4 below. Based on the collected data, construct a scatter plot to represent the relationship between the temperature and the water consumption. Then further assess the relation between these two parameters by compute the linear regression equation using least squares method and find its correlation coefficient.

As a factory manager, you are concem about the health of your workers. In this
regard, you have randomly sampled 15 staffs of your factory and recorded down
their water consumption under different working temperafures. In particular.
when they have already spent three hours under the working temperature The
collected data are shown in Table Q4 below. Based on the collected data,
construct a scatter plot to represent the relationship between the temperature and
the water consumption. Then, further assess the relation between these two
