Solution Steps

Step 1: Calculate the Sum of Scores

To find the mean score, we first calculate the sum of all the math scores:

\[ \sum_{i=1}^{N} x_i = 613 + 491 + 358 + 345 + 626 + 350 + 347 + 546 + 470 + 482 = 4628 \]

Step 2: Count the Number of Scores

Next, we determine the total number of scores, \( N \):

\[ N = 10 \]

Step 3: Calculate the Mean Score

The mean score \( \mu \) is calculated using the formula:

\[ \mu = \frac{\sum_{i=1}^{N} x_i}{N} = \frac{4628}{10} = 462.8 \]

Final Answer

The calculated mean score is \\(\boxed{462.8}\\).

Listed below are the heights ( cm ) of winning presidential candidates and their main opponents from several recent presidential elections. Find the regression equation, letting president be the predictor ( x ) variable. Find the best predicted height of an opponent given that the president had a height of 183 cm. How close is the result to the actual opponent height of 185 cm? Use a significance level of 0.05. President: 177, 188, 192, 188, 188, 183, 178, 183, 185 Opponent: 183, 173, 180, 188, 175, 185, 180, 182, 177 The regression equation is ŷ = + + + ( x. (Round the y-intercept to the nearest integer as needed. Round the slope to three decimal places as needed.)
