Final answer:
The mean of the sampling distribution of sample mean is 151 points and the standard deviation is 1.5 points.
Explanation:
To calculate the mean and standard deviation of the sampling distribution of sample mean, we can use the following formulas:
Mean of sampling distribution (μx) = Mean of population (μ)
Standard deviation of sampling distribution (σx) = Standard deviation of population (σ) / √Sample size (n)
For this question, the mean of the population is 151 points and the standard deviation is 9 points. The sample size is 36. Plugging these values into the formula, we get:
μx = 151 points
σx = 9 points / √36
= 9 / 6
= 1.5 points
