To find the point estimate of the mean score for the students, follow these steps:

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

2. Count the total number of scores.
There are 6 scores in total.

3. Calculate the sum of all the scores.
[tex]\( 650 + 550 + 380 + 720 + 710 + 550 = 3560 \)[/tex]

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

5. Round off the mean score to the nearest tenth.
[tex]\[ 593.3333333333334 \approx 593.3 \][/tex]

Hence, the point estimate of the mean score for the students, rounded to the nearest tenth, is [tex]\( 593.3 \)[/tex].
