# Question: A sample of n 7 scores has a mean

A sample of n = 7 scores has a mean of M = 5.

After one new score is added to the sample, the new mean is found to be M = 6. What is the value of the new score? (Hint: Compare the values for ∑X before and after the score was added.)

A population of N = 8 scores has a mean of m = 16. After one score is removed from the population, the new mean is found to be m = 15. What is the value of the score that was removed? One sample has a mean of M = 5 and a second sample has a mean of M = 10. The two samples are combined into a single set of scores. a. What is the mean for the combined set if both of the original samples have n = 5 ...For the following population of N = 6 scores: 11 0 2 9 9 5 a. Calculate the range and the standard deviation. (Use either definition for the range.) b. Add 2 points to each score and compute the range and standard deviation ...Calculate SS, variance, and standard deviation for the following population of N = 8 scores: 0, 0, 5, 0, 3, 0, 0, 4. Calculate the mean and SS (sum of squared deviations) for each of the following samples. Based on the value for the mean, you should be able to decide which SS formula is better to use.
