Problem

The following table shows students test scores on the first two tests in an introductory physics class.
\begin{tabular}{|c|c|c|c|c|c|c|c|c|c|c|c|c|}
\hline \multicolumn{10}{|c|}{ Physics Test Scores } \\
\hline \begin{tabular}{c}
First \\
test, $x$
\end{tabular} & 41 & 74 & 88 & 71 & 40 & 61 & 53 & 91 & 47 & 46 & 76 & 73 \\
\hline \begin{tabular}{c}
Second \\

Answer

The final predicted score for the student on the second test is \(\boxed{55.38}\)

Steps

Step 1 :To make a prediction for the student's score on the second test based on their score on the first test, we need to use the regression equation.

Step 2 :However, the regression equation is not provided in the question. We need to calculate the regression equation using the given data for the first and second test scores.

Step 3 :Using the given data, we calculate the predicted score for a student who scored 49 on the first test.

Step 4 :The predicted score is calculated to be 55.37890005913661.

Step 5 :We round the predicted score to two decimal places.

Step 6 :The final predicted score for the student on the second test is \(\boxed{55.38}\)
