To calculate a Z-score, not only are the standard deviation and mean needed, but also the 0 data point of interest 0 mode 0 median O variance Lets say Marco has a z-score of 1.96 on the SAT test. Which of these statements are true? (Hint: There can be more than one right answer.) C] About 2.5% of all students have higher scores than Marco. C] About 97.5% of all students have lower scores than Marco. C] Marco's score is 1.96 standard deviations above the mean. C] We find out there is a mix up, and Marco's name was associated with the wrong test. Somebody had just randomly written Marco's name on one of the tests on a huge pile of 1000 tests. out of these 1000 tests about 25 had a zscore of 1.96 or higher. So the probability of the person picking such a high scoring test was p = 0.025. (in other words 2.5 out of 100) C] About 97.5% of all students have higher scores than Marco.
