A normal distribution has a mean of µ = 80 with s = 20. What score separates the lowest 30% of the distribution from the rest of the scores?
A random sample of n = 4 scores is obtained from the normal population with µ = 20 and s = 4. Determine the probability that the sample mean will be greater than M = 22?
A population has m = 60 and m = 30. For a sample of n = 25 scores from this population, a sample mean of M = 55 would be considered an extreme value.
A sample of n = 9 scores has a standard error of 6. Determine the standard deviation of the population from which the sample was obtained?
A sample of n=7 scores has mean of M=5. After one new score is added to the sample, the new mean is found to be M=6. Determine the value of the new score?
