The average verbal sat score for the entire class of entering freshmen is 530. however, if you select a sample of 20 freshmen an
d compute their average verbal sat score you probably will not get exactly 530. what statistical concept is used to explain the natural difference that exists between a sample mean and the corresponding population mean?
<span>This difference is explained by the concept of statistical error. Statistical error simply means the difference between the 'true value' of some statistic (like the population mean) and the estimated value of some sample statistic (like a sample mean). Since no sample perfectly represents any population, there is always some statistical error involved when trying to use sample means to predict population means.</span>
Well, I saw my teacher solving the test herself, and then grading papers off of her paper that she solved. My teacher made the answer key for the tests.
it has to be $3.46 because you have to remember that tax is included and it could cost more than what you are paying for the sandwich or drink. but the other possible answer is $3.92 if you're not paying any tax.
