Question

People living in Urban and Rural areas were asked where they get their garden - care products. Suppose a test for independence is conducted to help determine if were a person lives (Urban or Rural) affects where they shop for garden- care products. A) Does the null hypothesis state that where a person lives is "independent" or "dependent" of where they shop for garden care products? B) When variables are dependent, are the observed values going to be relatively the "same" or "different" than the expected values? C) If where a person lives is independent of where they shop for garden care products, how many people that live in urban areas would you expect to shop at supermarket? (round to nearest tenth) D) What is the p-value for test for independence? (Round to nearest tenth) E) Is there enough evidence from this test to conclude that there is a relationship between where a person lives and where they shop for garden - care products? "yes" or "no"

Answer 1

A) The null hypothesis states that where a person lives is "independent" of where they shop for garden care products.

B) When variables are dependent, the observed values are going to be relatively "different" than the expected values.

C) If where a person lives is independent of where they shop for garden care products, the number of people that live in urban areas expected to shop at a supermarket would depend on the data given in the question. Unfortunately, there is no specific data provided to calculate the expected number of people.

D) The p-value for the test for independence is not provided in the question, so it cannot be determined.

E) Without the p-value or the results of the test for independence, it is not possible to conclude whether there is enough evidence to establish a relationship between where a person lives and where they shop for garden care products.
