Suppose the population mean of weights of apples in an orchard is μ = 150 grams with σ = 20 grams. Random samples of size n = 25 are taken.
What is the mean of the sampling distribution of x̄?
- Acheck_circle
150 grams
- B
20/√25 = 4 grams
- C
20 grams
- D
150/25 = 6 grams
Explanation
The mean of the sampling distribution of x̄ equals the population mean μ. Therefore μ_x̄ = 150 grams.
