... Calculations: Compute the percent in a sample and the associated margin of error [use m = z/2n_]. Use these two numbers to construct a confidence interval for the true percentage for the entire population. (pp. 23 & 24, 28) Compute the sample size needed to achieve a certain margin of error and the ...

... 8) You are surveying 110 Noble graduates about whether or not Pritzker prepares you for college. You find that 88 felt better prepared for college. You want to estimate this for all Noble graduates within 8% of the true proportion. How confident can you be in the interval? Write the sentence of inte ...

sampling distribution
... * The Standard Deviation of a sampling distribution for a mean is sigma/sqrt(n), but we rarely know sigma, so we estimate it with Sx, and then the standard deviation estimate is called a standard ...
