Question

enter values for x and y in the table to plot points in the graph. use the regression calculator to compare the teams number of runs with their number of wins. r=runs; w=wins the equation of the trend line is

Explanation:

Step1: Input data into regression calculator

Input the values of \( R \) (runs) as \( x - \) values and \( W \) (wins) as \( y - \) values.

Step2: Calculate regression equation

Using a regression calculator (such as in a graphing utility or statistical software), when we input the data points \((808,93)\), \((768,94)\), \((655,66)\), \((684,81)\), \((637,86)\), \((619,75)\), \((613,61)\), \((609,69)\), \((563,55)\) and perform a linear regression.

The formula for a linear regression equation is \( y=ax + b\), where \(a\) is the slope and \(b\) is the \(y -\) intercept.

After performing the regression calculation:
The slope \(a\approx0.13\) and the \(y -\) intercept \(b\approx - 10.3\)

Answer:

\(y = 0.13x-10.3\)
