PLEASE ANSWER ALL QUESTIONS FOR THUMBS UP, ELSE DONT BOTHER.

A surveyor is hoping to learn more about Georgia's 5th Congressional District. Based on US Census data, she knows that 59.3% of residents in Georgia 5 identify as "Black or African-American", 32.4% identify as "white", and the remainder identify with some other ethnicity. A recently released study claimed a random sample of residents 524 African-American respondents, 344 White respondents, and 84 other. Perform a chi-squared goodness of fit test. As usual, round each value to the nearest 0.01 as you type it into this assignment, but never round your work in progress. How many degrees of freedom? Complete the table EthnicityExpected Actual (f-e)e African-American 524 White 344 Other 84 chi-squared test statistic- p-value Is there evidence that the survey respondents are not split as expected amongst the demographics of Georgia's 5th district? Answer yes" or "no or no

Explanation / Answer

1)

chi-square TS = 7.32277

p-value

df = r-1 = 2

p-value - P(X^2 > 7.32277) = 0.03

since p-value is less than 0.05

we reject the null

hence

Yes, there is evidence that the survey residents are not split as expected

2)

df = r-1 = 2

Ts = 0.779626

p-value = 0.68

No
