In the last mayoral election in a large city, 53% of the adults over the age of 65 voted Republican. A researcher wishes to determine if the proportion of adults over the age of 65 in the city who plan to vote Republican in the next mayoral election has decreased. Write the hypothesis statements for this situation below.
H0:
HA:

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870

we would need a picture of the quadrilateral in order to answer the question. also, it seems that the question is missing some components.

(hint): the answer is in the question.
