Z-Score

Find the z-scores corresponding to each of the following values:

A normal distribution of scores has a standard deviation of 10. Find the z-scores corresponding to each of the following values: Match each item to a choice: A score that is 20 points below the mean. A score of 80, where the mean score of the sample data values is 50. A score of 80, where the mean score of the sample data values is 30. A score that is 100 points below the mean. A score that is 15 points above the mean. A score of 60, where the mean score of the sample data values is 40. A score that is 10 points below the mean. A score that is 30 points below the mean. Choices: Z=3 Z = -2 Z = 5 Z = 1.5 Z = =1 Z =2 Z=-3 Z =-10Question 1 of 11 1 Point 68% of the marks in a test are between 51 and 64 Assuming this data is normally distributed, what are the mean and standard deviation? Select the correct response: Mean = 57.5 S.D. = 6.5 Mean = 57.5 S.D. = 13 O Mean = 57 S.D. = 6.5 O Mean = 57 S.D. = 7 Continue >
