Suppose a set of data has a sample mean of 106 and a sample standard deviation of 19.8. What is the Z-score for the value 122.0? Round the 2-score to two decimal places. Your Answer: Answer
Consider the given data set.n = 12 measurements: 9, 8, 1, 3, 5, 5, 5, 4, 8, 5, 4, 0Find the mean. 4.75Find the standard deviation. (Round your answer to four decimal places.) 2.701Find the z-score corresponding to the minimum in the data set. (Round your answer to two decimal places.)z = Find the z-score corresponding to the maximum in the data set. (Round your answer to two decimal places.) z = Multiple Choice 5. Do the z-scores indicate...
Question 4 0.5 pts A data set has a mean of 44. In this data set, a raw score X-40 corresponds to the standardized score z-1. What is the standard deviation for this data set? Hint:take advantage of the formula for Z-score Question 5 0.5 pts A data set has a standard deviation of 2.5. In this data set, a raw score X-30 corresponds to the standardized score z = 1.30. What is the mean of this data set? Hint:take...
A set of data values is normally distributed with a mean of 65 and standard deviation of five. Determine the Z-score of 78. a. -1.12 b. 2.6 c. 1.12 d. -2.6
Use the magnitudes (Richter scale) of the earthquakes listed in the data set below. Find the mean and median of this data set. Is the magnitude of an earthquake measuring 7.0 on the Richter scale an outlier (data value that is very far away from the others) when considered in the context of the sample data given in this data set? Explain. Click the icon to view the earthquake Richter scale data. Find the mean and median of the data...
Given the following 2 sets of experimental data find the sample mean, sample standard deviation, and sample variance using formulas shown in class. Then, find a histogram for the range of 0.6 to 2.4 with intervals of width 0.2. Finally, plot a normal distribution with the calculated mean and standard deviation. Hint: You must start by putting the two data sets into a single vector. datal (0.9 1.32 1.96 1.85 2.29 1.42 1.35 147 1.74 1.82 1.3 147 192) data2...
#4 (4a) You have a data set with a mean of 50 and a standard deviation of 10. If you add 3 to every data point, what will be the new values for the mean and standard deviation. Briefly explain your answer. (4b) The standardized score for the minimum of a data set is Zmin median is zmed = -0.6, and the standardized score the maximum of the data set is zmin +6.8. Based on this information alone, describe the...
