To find the point estimate of the mean score for the students, we'll use the scores provided in the table. Here are the steps:

1. List the scores: 650, 550, 380, 720, 710, 550.

2. Calculate the total score by adding all the individual scores:
[tex]\[ 650 + 550 + 380 + 720 + 710 + 550 = 3560 \][/tex]

3. Determine the number of students whose scores are provided, which is 6.

4. Calculate the mean score by dividing the total score by the number of students:
[tex]\[ \text{Mean Score} = \frac{3560}{6} = 593.3333333333334 \][/tex]

5. Round off the mean score to the nearest tenth:
[tex]\[ 593.3 \][/tex]

Therefore, the point estimate of the mean score for the students is:

[tex]\[ 593.3 \][/tex]
