Question
Explanation / Answer
1) As a general rule, sample sizes equal to or greater than 30 are considered sufficient for the central limit theorem to hold, meaning the distribution of the sample means is fairly normally distributed, even if the underlying distribution is not normal
Answer: option C
2) Answer Option B: The sampling distribution of x_bar is normal or approximately normal with mu_xbar = 31 and
sigma_xbar = 3/sqrt(44) = 0.452
Formula: sigma_xbar = sigma/sqrt(n)
