A December 2009 poll asked a random sample of people whether they thought their country was heading in the right direction. Each
respondent answered "Right Direction" or "Wrong Direction" and was classified as Republican, Democrat, or Independent. If we were interested in testing whether party affiliation was associated with the answer to the question, would this be a test of homogeneity or of independence? Explain.
This would be test of independence because it contain only one sample test
Step-by-step explanation:
Test of independence determine two factors are independent or not
For example
if we do a test of independence
null hypothesis : H 0: Being a cell phone user while driving and receiving a speeding violation are independent events. If the null hypothesis were true, we would expect about 28 people to use cell phones while driving and to receive a speeding violation.
Therefore in the given question Each respondent answer that it might be in "Right Direction " or "Wrong Direction".
Here, it is given that the bag contains 25 paise coins and 50 paise coins in which, 25 paise coins are 6 times than that of 50 paise coins. Also, the total money in the bag is Rs. 6.
Hence, we can see that, here, we have been given the linear equation be;
Let the number of coins of 50 paise will be $ x $ and the number of coins of 25 paise will be $ 6x $ as given. . .
Hence,
Hence, the number of 50 paise coins will be <u>2</u>. And, 6 times of two be;
Hence, the number of 25 paise coins will be <u>12</u>.
