TrueFalse 6 points each 1 The sampling distribution of a sam

True/False (6 points each)

1. The sampling distribution of a sample statistic is the probability distribution of the population of all possible values of the sample statistic. (Ch8)

2. If a population is known to be normally distributed, then it follows that the sample standard deviation must equal population standard deviation. (Ch8)

3. If p=.8 and n=50, then we can conclude that the sampling distribution of the proportions is approximately a normal distribution. (Ch8)

4. The standard deviation of the sampling distribution of the sample mean is the same as the population standard deviation. (Ch8)

5. The sample standard deviation s is an unbiased estimator of the population standard deviation. (Ch8)
