Question

What would be a good estimate of the mean for the data shown below? Stem Leaves 6 7 8 9 10 090 100 080 68 8 Test Scores O 0, 6, 8, 8, 6, 6, 7, 7, 8, 8, 9 0, 0, 0, 0, 0 610 60 years old​

Answer 1

A good estimate of the mean for the data shown is around 70.

Step-by-step explanation:

A stemplot is provided, showing the distribution of test scores.

The stemplot indicates that most scores fell in the 60s, 70s, 80s, and 90s. Since the stemplot does not provide specific values for the leaves, we can estimate the mean based on the stems only. From the stemplot, it appears that the majority of scores are in the 70s.

Therefore, a good estimate of the mean for the data would be around 70.
