Question

Each student in school is growing a plant. Robert takes a random sample of 8 plants and measures the heights in inches. His data is shown.
5, 3, 8, 5, 9, 3, 5, 2
Given this data, what is the best estimate for the mean height of all the plants in the school? Explain using complete sentences and proper grammar.

Answer 1

Answer:

Mean = Sum of observations / No. of observations

Sum = 5+3+8+5+9+3+5+2 = 40

No. of observations = 8

Mean = 40 / 8 = 5
