If a student scored 76 points on a test where the mean score was 80.5 and the standard deviation was 5.1. The student's z score is ________. Explanation with math please
The scores on a certain test are normally distributed with a mean score of 53 and a standard deviation of 2. What is the probability that a sample of 90 students will have a mean score of at least 53.2108? 0.8413 0.3174 0.3413 0.1587
A particular standardized test has a mean score of 455 with a standard deviation of 112. A student received a z-score of 1.07 on this test. Determine the student's actual score. Round to the nearest whole number.
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...

3. Calculate the Z score, given x 55,0-2.5, and -28 Ans: 4. Calculate x , given ze-1.45, σ 30.5, and μ-40 Ans: 5. A student scores 74 on a geography test and 282 on a mathematics test. The geography test has a mean of 80 and a standard deviation of 5. The mathematics test has a mean of 300 and a standard deviation of 12. If the data for both tests are normally distributed, on which test did the student...
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.
