To start with we need to find what the current range median mode and mean is for the first 4 results: 80, 88, 94, 98 Current range = 98-80 =18 current median = (88+94)/2 =91 Current mode= there is not one most frequent score so they're all the mode Current mean=(80+88+94+98)/4 =90 When we add the additional score of 85 We have 80,85,88,94,98 Range doesn't change (highest score and lowest score is still the same)…

### What does an IQ of 135 mean?

### Abby has received scores of 85 88 87 and 80 on her algebra tests. What is the minimum score she must receive on the fifth test to have an overall test score average of at least 82?

Let the minimum score she must receive on the 5th test be equal to "x." First you need to add up all the test scores. Then, you divide that sum by the number of test scores, this will give you your average score (which we want to be at least 82). Solve for x. (85 + 88 + 87 + 80 + x) ÷ 5 = 82 (340 + x) ÷ 5 = 82 (340…

### What does an IQ score of 137 mean?

Attaining a score of 137 on a legitimate (psychologist-supervised) test (e.g. Stanford-Binet) with a standard deviation of 16 ranks one at the 99th percentile, objectively, assuming a mean score of 100. In reality, global mean IQ is ostensibly ~90 (SD16; 88, SD15); thusly, an SD16 score of 137 (SD15, 135) places one at approximately the 99.9th percentile amongst all people, worldwide. An individual scoring 137 (SD16) is eligible for admission to Intertel (and, of course…

### Alicia's average score on her five tests is 88 points The score range for each test is 0 point to 100 points inclusive What is the lowest possible score that Alicia could earned on 1 of 5 test?

### What is a passing score on USPS 430 exam?

### What is the mean of 76 54 92 88 76 88 75 93 92 68 88 76 76 88 80 70 88 and 72?

When they ask for the 'mean' they are really asking for the average of all those numbers. All you have to do is add those up: 76+54+92+88+76+88+75+93+92+68+88+76+76+88+80+70+88+72= 1440 And then divide by how many numbers we added up. In this case, we added up 18 different numbers. So: 1440 / 18 = 80 80 is your 'mean' or average number.
