The income of residents of Chicago, IL has a bell shaped and symmetric histogram, with a mean of $65,000 and a S.D. of $13,000. 1) What percentage of residents have an income more than $78,000 or less than $52,000? 2) what percentage of residents have an income between $39,000 and $91,000? 3) What percentage of residents have an income less than $104,000? 4) What percentage have an income more than $65000? 5) Less than $26,000 Hint: you need to draw a curve for each part 1-4, and calculate the mean ± 1, 2, 3 S.D.
Because the confidence interval limits v 0, it appears that the two proportions are V Because the confidence interval limits include V values, it appears that the proportion of people over 55 who dream in black and white is V the proportion for those under 25. c. An explanation for the results is that those over the age of 55 grew up exposed to media that was displayed in black and white. Can these results be used to verify that explanation? O A. No. The results speak to a possible difference between the proportions of people over 55 and under 25 who dream in black and white, but the results cannot be used to verify the cause of such a difference. O B. No. The results speak to a possible difference between the proportions of people over 55 and under 25 who dream in black and white, but the results are not statistically significant enough to verify the cause of such a difference. O C. Yes. The results can be used to verify the given explanation because difference in proportions is…
