Question 1 part a) (Can also see attachment)

A sociologist hypothesizes that the average annual income of households in a particular large city is less than $30,000 per year. To test her hypothesis, she samples 500 households in the city and determines the income of each.

Determine which statement describes the population, the varable of interest, the sample, and the inference by inputting p, v, s, or i respectively beside the appropriate statement.

i) The 500 households selected by the sociologist.

ii)The set of all households in the city.

iii) The sociologist wants to estimate the average income of the households in the city in order to determine whether it is less than $30,000

iv)The total annual income of each household.

Part b)

"Cola Wars" is the popular term for the intense competition between Coca-Cola and Pepsi displayed in their marketing campaigns. Their campaigns have a featured movie and television stars, rock videos, athletic endorsements, and claims of consumer preference based on taste tests. Suppose, as a part of a Pepsi marketing campaign, 1,000 cola consumers are given a blind taste test (i.e. a taste test in which the two brand names are disguised). Each consumer is asked to state a preference for brand A or brnad B. Determine which statement describes the population, the varable of interest, the sample, and the inference by inputting p, v, s, or i respectively beside the appropriate statement. i)The preferences of the consumers in the sample can be used to estimate the percentage of all cola consumers who prefer each brand.

ii)Cola preference.

iii)The 1,000 cola consumers selected from all the cola consumers.

iv)The collection or set of all consumers.
