Can you help me with question 2,3,4,5,6,7,9,10 and 11

PROBLEMS 1. What information is provided by the sign (+/-) of 7. A population has a mean of p. = 60 and a standard a z-score? What information is provided by the deviation of o = 12 numerical value of the z-score? a. For this population, find the z-score for each of the 2. A distribution has a standard deviation of o = 10. following X values Find the z-score for each of the following locations X = 69 X = 84 X = 63 in the distribution. X = 54 X = 48 X = 45 a. Above the mean by 5 points. b. Above the mean by 2 points. b. For the same population, find the score (X value) C. Below the mean by 20 points. that corresponds to each of the following z-scores. d. Below the mean by 15 points. z = 0.50 z = 1.50 z = -2.50 3. For a distribution with a standard deviation of z = -0.25 z = -0.50 z = 1.25 or = 20, describe the location of each of the following z-scores in terms of its position relative to the mean. 8. Find the z-score corresponding to a score of X = 45 For example, z = + 1.00 is a location that is 20 points for each of the following distributions. above the mean. a. p. = 40 and o = 20 1.
