The defending attorney Mr. Justin Case was interested in how a lengthy trial could affect how long a jury would deliberate on a case (and see if he should just cut to the chase). He observed a sample of courtroom trials and noticed the following: Days in Trial (X) 5 2 6 4 5 6 2 4 2 1  Hours Deliberation (Y) 4 4 1 3 1 3 9 2 3 7 2) What is the Y-intercept?

Suppose a researcher collects data on the gas mileage, measured in miles per gallon, for both city and highway driving in 35 cars. The data is plotted with city gas mileage on the horizontal axis and highway gas mileage on the vertical axis. The 1965 Triumph Herald is an outlier in the ?‑direction. What must be true about this car? A. This car is an influential observation. B. The highway gas mileage for this car is much higher or lower than other cars in the data set that have similar city gas mileage. C. The absolute value of the residual of this car is large. D. The city gas mileage for this car is much higher or lower than the rest of the cars in the data set. E. The highway gas mileage for this car is much higher or much lower than the rest of the cars in the data set.

You work as a data scientist for a real estate company in a seaside resort town. Your boss has asked you to discover if it's possible to predict how much a home's distance from the water affects its selling price. You are going to collect a random sample of 9 recently sold homes in your town. You will note the distance each hame is from the water (denoted by X, in km) and each home's selling price (denoted by y, in hundreds of thousands of dollars). You will also note the product X-y oaf the distance from the water and selling price for each hame.

Please explain in 9th grade math:) Also what effect does these variables have in each other? Why do you think this is realistic?

Sometimes we have data that can be paired together, such as height and weight of an individual. When two variables are measured and paired together, we have what we call paired data. When we have paired data, we can plot the results using a scatterplot. This will give us a visual to determine if there is a relationship between the variables of interest.  For two variable relationships, we can often report the data as ordered pairs in (x, y) format. Our x-variable in this case is known as the explanatory variable, and the y-variable is known as the response variable. We use values of x to predict y.  If there appears to be a linear relationship between the two variables, we can create a least squares regression line. This is a line that “best” fits the dataset we have. The result will be a linear equation and we can use this equation to predict future values.   For simple linear regression (ordered pairs with only two variables), the general form of a regression line follows:�̂=β0+β1�,…
