The data provided aims to predict the selling price of houses in Newburg Park, Florida, based on their distance from the beach. The table includes data for sixteen homes sold over the past year. It features three columns: 1. **Distance from the beach, $x$ (in miles)**2. **Selling price, $y$ (in thousands of dollars)**3. **Product of distance and selling price, $xy$**The table is as follows:| Distance (miles) | Selling Price (thousands of dollars) | $xy$ ||------------------|--------------------------------------|-------|| 5.7 | 289.6 | 1650.72 || 9.1 | 238.6 | 2171.26 || 10.6 | 283.0 | 2999.8 || 7.6 | 209.0 | 1588.4 || 17.8 | 233.2 | 4150.96 || 6.0 | 240.0 | 1445.4 || 6.6 | 275.0 | 1815 || 12.6 | 269.1 | 3659.76 || 3.8 | 317.0 | 1201.2 || 11.3 | 207.7 | 2346.01 || 8.9 | 233.0 | 1508.5 || 12.1 | 212.0 | 2568.4 || 15.0 | 229.6 | 2752.98 || 10.1 | 277.0 | 2803.12 || 9.9 | 202.4 | 2003.76 |**Scatter Plot Analysis (Figure 1):**- **X-Axis**: Represents the distance from the beach in miles.- **Y-Axis**: Represents the selling price in thousands of dollars.- The points on the scatter plot show the relationship between the two variables, where a general trend can be observed.The scatter plot indicates potential trends in how the selling price decreases as the distance What is the slope of the least-squares regression line for these data? Carry your intermediate computations to at least four decimal places and round your answer to at least two decimal places. (If necessary, consult a list of formulas.)[There is a text input field and two buttons: one with a recycle bin icon and another with an 'X' and a circular arrow icon.]

The slope of the least squares regression line is calculated by using the formula : Slope = (NΣxy –…

We want to predict the selling price of a house in Newburg Park, Florida, based on the distance the house lies from the beach. Suppose that we're given the data in the table below. These data detail the distance from the beach (x, in miles) and the selling price (y, in thousands of dollars) for each of a sample of fifteen homes sold in Newburg Park in the past year. The data are plotted in the scatter plot in Figure 1. Also given is the product of the distance from the beach and the house price for each of the fifteen houses. (These products, written in the column labelled "xy", may aid in calculations.)

Suppose a researcher collects data on the air pollution levels, measured in milligrams per cubic meter, for both urban and rural areas in 35 states. The data is plotted with urban air pollution levels on the horizontal axis and rural air pollution levels on the vertical axis. Nevada is an outlier in the ?x‑direction. What must be true about this state? The urban air pollution levels for this state are much higher or lower than the rest of the states in the data set. The rural air pollution levels for this state are much higher or much lower than the rest of the states in the data set. This state is an influential observation. The rural air pollution levels for this state are much higher or lower than other states in the data set that have similar urban air pollution levels. The absolute value of the residual of this state is large.
