Question

The scatterplot contains data points, showing the number of hours a coffee shop is open (x) and the number of customers served (y).A graph with time open (hours) on the x-axis and customers on the y-axis. Line c is the line of best fit.Using the least-squares regression method, which is the line of best fit?line aline bline cline d

Answer 1

The line of best fit is line c.

The line of best fit is the line that minimizes the sum of the squared distances between the data points and the line. Based on the graph, line c appears to be the line of best fit. It is the closest to most of the data points and minimizes the overall distance between the points and the line.

Lines a, b, and d do not fit the data as well as line c. Line a is too steep, line b is too shallow, and line d is not close to enough of the data points.

Therefore, the answer is c.

Answer 2

Given:

The scatterplot contains data points, showing the number of hours a coffee shop is open (x) and the number of customers served (y).

Required:

We need to find that which line is the best fit

Step-by-step explanation:

The line that best tries to show the relationship that existing in a given set of data.

The line C is the best fit because the values are known to more fitted to the line when it is drawn, the dits are more clustered at line C

Final answer:

Line C
