Hello!
Answer:
The mean cannot be calculated
Explanation:
→ We want to calculate the mean of the data 3, 1, 2, 5+, 2, 4.
→ We know that a value of this data is 5 or +.
→ The value of the mean varies according to the value of the value "5+" because the value "5+" can be 5 or 6, or 7...
→ So the mean cannot be calculated.
Conclusion:
The mean cannot be calculated.
