I need just need the answers for these questions:
1 – Samples of size are selected from a population with µ with ð . What is the standard error for the distribution of sample means?
2 – If random samples, each with , are selected from a normal distribution with µ and ð, then what is the standard error for the distribution of the sample mean?
3 – If random samples, each with n-36 scores, are selected from a normal population with µ and ð, how much difference, on average, should there be between a sample mean and the population mean?
4 – A random sample of scores is selected from a population with µ and ð. On average, how much difference would you expect between the sample mean and the population mean?
5 – Which of the following samples would produce a standard error of 3 points?
6 – A sample of scores is determined to have a standard error of 2 points. What is the standard deviation for the population from which the sample was obtained?
7 – What happens to the standard error of M as sample size increases?
8 – Which combination of factors will produce the smallest value for the standard error?
9 – If a sample of scores is obtained from a population with µ and ð12, then what is the z-score corresponding to a sample mean of ?
10 – A sample from a population with µ and ð has a mean of .If the sample mean corresponds to a .00, then how many scores are in the sample?
11 – For a particular population, a sample of scores has a standard error of 4. For the same population, a sample of scores would have a standard error of _____________________.
12 – A sample of scores has a standard error of 6. What is the standard deviation of the population from which the sample was obtained?
13 – For a normal population with µ and ð which of the following samples is least likely to be obtained?
14 – A random sample of scores is obtained from a normal population with µ and ð. What is the probability that the sample mean will be greater than ?
15 – A random sample of scores is obtained from a normal population with µ and ð. What is the probability that the sample mean will be within 2 points of the population mean?
16 – A sample of scores is selected from a population with µ and ð. If the sample mean is , what is the z-score for the sample mean?
