GinnyAnswer
To find the point estimate of the mean score for the given 6 students, follow these steps:

1. List the scores:
- Julia: 650
- Andrew: 550
- Jason: 380
- Cathy: 720
- Jessica: 710
- Robert: 550

2. Sum the scores:
- Sum = 650 + 550 + 380 + 720 + 710 + 550

3. Calculate the total sum:
- Sum = 3560

4. Determine the number of students:
- Number of students = 6

5. Calculate the mean score:
- Mean score = Total sum of scores / Number of students
- Mean score = 3560 / 6

6. Compute the mean score:
- Mean score ≈ 593.3

Thus, the point estimate of the mean score for the students is

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