Ten different families are tested for the number of litres of water they use each week before and after viewing a conservation video.We want to see if there is strong evidence that the conservation video changes people's water consumption rate.A t-test of the null hypothesis of no difference has a t-statistic of -2.894 with a P-value of 0.0178.Interpret this result by explaining the meaning of the P-value.
Water Consumption Rate
The measurement of the volume of water used by an entity over a specific period.
Conservation Video
Visual media content created to raise awareness about the importance of protecting natural habitats and species.
P-value
The probability of observing results as extreme as those measured when the null hypothesis of a study is true, used in hypothesis testing.

Final Answer :
If there is no difference in average water consumption rates after viewing the conservation video,the chance of seeing a difference as large or larger than the one observed is about 1.78%.
