A student received a score of 3 on a test, which yields a z-score of 0.51 What percent of the sample group will have a score at or below their score?
Let Z denotes a standard normal variable.
Now,
So, Percentage of the sample group will have a score at or below their score = 69.4974%

Calculate the Z-score. A student earns a score of 53 on a test where the mean is 41 and the standard deviation is 6. Enter the Z-score rounded to the nearest hundredth.
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...
2. Suppose a student finds out that her score on her math test was z = +1.3. How would you explain this score to the student?

If a person received a test score that is in the top 32% of all test scores, the person’s z-score must be at least 0.46. How did we come up with 0.46? What is the formula used?
Raul received a score of 77 on a history test for which the class mean was 70 with a standard deviation of 3.
