, True or False: A sampling distribution is a collection of a large number of
samples - 🧠ANSWER ✔✔true
In general, when calculating a point estimator using samples, we -
🧠ANSWER ✔✔prefer unbiased estimates because they represent
parameters
We interpret the standard error of the mean as - 🧠ANSWER ✔✔standard
deviation of the sampling distribution of means
The mean of the sampling distribution is - 🧠ANSWER ✔✔equal to the
population mean
The standard error of the sampling distribution of means is - 🧠ANSWER
✔✔population standard deviation / square root of n
If a random sample is taken from a population that is normally distributed,
the sample will be - 🧠ANSWER ✔✔distributed normally every time
Regardless of the population, if n is large, the sample distribution will be
normal because of - 🧠ANSWER ✔✔Central Limit Theorem
The Central Limit Theorem is considered - 🧠ANSWER ✔✔to be one of the
most important ideas in statistics
