Answer:
The mean (μ) of the sampling distribution of the sample mean is equal to the population mean, which is 20 pounds.
Explanation:
The standard deviation (σ) of the sampling distribution of the sample mean is equal to the population standard deviation divided by the square root of the sample size:
σ = 5 / sqrt(5) ≈ 2.24 pounds (rounded to two decimal places)
Therefore, the mean of the sampling distribution of the sample mean is 20 pounds and the standard deviation is approximately 2.24 pounds when samples of size 5 are taken from the population of watermelons with a mean of 20 pounds and a standard deviation of 5 pounds.
