### Investigating Collisions in Amusement Park Bumper CarsA study was conducted to explore the number of possible collisions between bumper cars at an amusement park. It's assumed that no two bumper cars can collide more than once. The intention was to determine which mathematical curve best fits the data presented.#### Data TableA table was created to record the number of possible collisions based on the number of bumper cars:| # of Cars | Possible Collisions ||-----------|---------------------|| 1 | 0 || 2 | 1 || 3 | 3 || 4 | 6 || 5 | 10 || 6 | 15 || 7 | 21 |#### Curve Fit OptionsBased on the data gathered, the following are the provided curves to determine the best fit for the data:1. \( y = 0.5x^2 - 0.5x \)2. \( y = -0.5x^2 + 0.5x \)3. \( y = 3.5x - 6 \)4. \( y = 6x - 3.5 \)#### AnalysisTo determine which curve best represents the data, evaluate each curve's appropriateness based on how closely it aligns with the data from the table provided.**Graphical Representation Explanation:**If you were to plot the data points from the table on a graph, you would plot \( x \) representing the number of cars and \( y \) representing the possible collisions.To match the data with any of the equations given:1. For \( y = 0.5x^2 - 0.5x \), substitute each \( x \) value to see if the corresponding \( y \) value matches the data.2. Repeat this process for each equation until you find the one that aligns perfectly with the data.**Educational Insights:**Analyzing such data helps in understanding the practical application of quadratic functions in real-life scenarios such as amusement parks. This example also illustrates the importance of modeling and curve fitting in statistical analysis.

The difference between a regression weight and a beta weight is: A regression weight assumes linearity. A beta weight is for the population while a regression weight is for the sample. A regression weight is less biased. A beta weight is a standardized regression weight.

Freshcrim specializes in the sales of ice cream from street trolleys in the centers of many cities. Some factorsthat may determine the sales of ice cream are: the atmospheric temperature, the location of the trolley, therain and the humidity. However, there exists a hypothesis that the sales of ice cream during the summer aresignificantly correlated only with atmospheric temperature. They defined two variables: X : the meanatmospheric temperature and Y : the sales. They considered the month of July of this year in a randomsample of 30 cities. For each city in the sample, let x be the mean temperature in degrees Fahrenheit and ythe mean sales per day in dollars per 100,000 residents. The data are given below. A regression model wasrun, with Y as the dependent variable and X as the independent variable.
