Unit 3-Water Usage Project

The importance of this project is to see the amount of water usage. Water usage is very crucial for our daily lives but it's also very important to conserve and protect this valuable resource. The amount of water usage depends on the population/mount of people in states,households,citys and,places. If you have a high population in state or city or a lot of people in your household the higher amount of water usage. To collect out data we completed a set of questions from a few websites or estimated the total amount of our water usage a day. We also send home surveys for families to fill out.

As I analyze the scatterplot of the district wide graph I can see the that majority of the households don't exceed 780 gallons of water per day. The slope and Y-Int show the relationship between how many people live in the household and the total of gallons of water used a day by one family/household. The LSRL purpose is a ine that goes through the right spot of the data and describes how a reponse of a variable changes an explanotory variable. I have a family of 5 and use around 600-700 gallons a day which is above the LSRL. If the R and R^2 is closer to 1 then we have a strong LSRL. If the line is closer to 0 then we have a weak/negative LSRL. And in this case this LSRL shows that its too small/weak.

The less people the less water being used, the more people the more water being used. Confounding variables in the data is reasons why water is being used in hoseholds. For example showers,washing hands,dish washers and etc.... These confounding variables all have a impact on the water usage (how much water is being used per household). Which shows us as well that our  graph is casual because the amount  of water being used directly impactes the the # of people in the house. I believe the story being told is that water is being wasted and conserved a lot especially when there is a lot of people living in one household with effects the the amount of water.

We certtainly can use this information to find our district which would be similiar but for the whole school it might be a little difficult we woulldnt have a good corelation.I believe we can not apply our models information to our city. Because according to our city data, a roseville person would ue 612,211 gallons of water daily. Unlike our district where one person uses around 278,609 gallons of water.  The city of roseville estimate does not fit with our districts data so we cant apply our odels information to our city.I feel like that you can use the state it just might be very scattered due to people living in different locations in that state and probably would have a weak LSRL. The state of California uses 38 billion gallons of water a day as a whole and the city of roseville uses 612,211 gallons of water daily a person. I belive the state is reasonable because on top of all the households we have waterparks,swimming pools, and etc... No state is copared to california in the amount of water used.
