Below the mean by 24 points. d. Below the mean by 8 points. For a population with u = 50 and o= 8, find the z-score for each of the following X values. a. X= 54 b. X= 62 c. X= 52 d. X=...
In a normal distribution, the mean corresponds to: Standard Score: z = Percentile: Which of the following statements are TRUE about the normal distribution? Check all that apply. A data value with z-score = -1.5 is located 1.5 standard deviations below the mean. The mean corresponds to the z-score of 1. The Empirical Rule only applies when a value is exactly 1, 2, or 3 standard deviations away from the mean. A z-score is the number of standard deviations a...
Suppose that student’s z score is 3.00 what does this mean? discuss in terms of units of standard deviation It means the value defined by z-score is 3 standard deviations away from the mean value. Discuss in terms of its percentile score. In terms of percentile score, its mean amount of data lies below the value. Z=3 represent the 99.87 the percentile. 4. How does this student’s z score differ from another student whose z score is -3.00 5. If...
Identify the Z-Score value corresponding to each of the following locations: Below the mean by a standard deviation of 1 Above the mean by a standard deviation of 1 and 1/2 Below the mean by standard deviation of 3/4 Above the mean by a standard deviation of 2 and 7/8 a. Z = 1.00 Z = 1.50 Z = .75 Z = 2.875 b. Z = -1.00 Z = +1.50 Z = -.75 Z = +2.875 c. Z = +1.00...
NO HANDWRITTEN ANSWERS PLEASE For the standard normal curve, find the z-score that corresponds to the 30th percentile. Find the z-score for which 99% of the distribution’s area lies between –z and z. Assume that the heights of men are normally distributed with a mean of 69.0 inches and a standard deviation of 2.8 inches. If 64 men are randomly selected, find the probability that they have a mean height between 68 and 70 inches. An airline reports that it...
A z score of 1.25 represents an observation that is a) 1.25 standard deviation below the mean. b) 0.25 standard deviations above the mean of 1. c) 1.25 standard deviations above the mean. d) both b and c Assume that your class took an exam last week and the mean and standard deviation of the exam were 85 and 5, respectively. Your instructor told you that 30 percent of the students had a score of 90 or above. You would...
For a normal population with an average of 60 and a standard deviation of 12 what is the probability of selecting a random sample of 36 scores with a sample mean greater than 64? p(M greater than 64)? a 50% b .9772 or 97.72 % c. .8777 or 87.77% d. .0228 or 2.28% A population has a mean of 50 and a standard deviation of 5, find the z-score that corresponds to a sample mean of M=55 for a sample...
Can someone please explain how to calculate the z-score? I was using the formula z=(x-mean)/standard deviation, but it keeps getting marked incorrect. In the following data setof tire pressures(psi), determine the Z-score of 83. 2447 45 3 52 | 80 83 58 41 | 81 | 49 97 36 86 6 25 93 2 34 70 Z-score = [three decimal places]
