Find the sample mean and sample standard deviation of your data. What is the Z score? Pick three bills from the last 12 months and change the values into z-scores. What does the z-score tell you about that particular month? Between what two values would be considered a normal bill? Remember, being within 2 Standard Deviations is considered normal. Are any of your bills in the last 12 months unusual? Very unusual? Are there times when you would accept an...

find the Z score for the value of 74 from simple with a mean of 86 and a standard deviation of 15.
To find it's Z-score, the sample data must be shifted by subtracting the mean of the population and then rescaled by dividing by the standard deviation of the population. True False
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...
25.) Find the z-score corresponding to the given value and use the z-score to determine whether the value is unusual. Round the z score to the nearest tenth if necessary. Show work for finding z score 26. Identify which of these types of sampling is used Find the z-score corresponding to the given value and use the Z-score to determine whether the value is unusual. Round the z-score to the nearest tenth if necessary. You must show your work for...
