Question

d. What is the SE of the sample average? $ (round to 2 decimal places) e. Suppose we created a 95% CI for the average amount of money Illinois adults spend on coffee each month. To which of the following populations can we apply that 95% CI? All US adults All adults in the state of Wisconsin All females in the US None of the above f. Suppose we take another poll in the entire US instead of just Illinois. In order to obtain the same accuracy as in the first poll only in IL, the sample size of the second poll in the US should: Decrease need more info to answer Increase Stay the same g. If the study asked the 1048 Illinois adults whether or not they drink coffee, the relevant box model would contain tickets with: Numbers ranging from about 0 to 100 not enough info Only "1"s and "0"s h. If the researcher increased the sample size (n) by a factor of 100, the SE for the average would be divided by 10 be divided by 100 stay the same be multiplied by 10 be multiplied by 100 i. If the researcher increased the sample size (n) by a factor of 100, the length of a 95% confidence interval would be divided by 10 be divided by 100 stay the same be multiplied by 10 be multiplied by 100
