Q:

Suppose a random sample of​ 1,220 adults in a certain country were asked about their opinion regarding federal spending on public education. Respondents were asked whether federal spending on public education was​ (a) too​ low, (b)​ adequate, or​ (c) too high. Respondents were classified by income level. Choose the correct hypotheses to test whether there is an association between the response to the question and income level.A. Upper H 0H0​:Among adults in the​ country, opinions about federal spending on education and income level are associated.Upper H Subscript aHa​:Among adults in the​ country, opinions about federal spending on education and income level are independent.B. Upper H 0H0​:There is no difference between the proportions of adults in the country who responded​ (a), (b) or​ (c) to the opinion question.Upper H Subscript aHa​:There is a difference between the proportions of adults in the country who responded​ (a), (b) or​ (c) to the opinion question.C. Upper H 0H0​:Among adults in the​ country, opinions about federal spending on education and income level are independent.Upper H Subscript aHa​:Among adults in the​ country, opinions about federal spending on education and income level are associated.D. None of these

Accepted Solution

A:
Answer:A. Upper H 0H0​: Among adults in the​ country, opinions about federal spending on education and income level are associated. Upper H Subscript aHa​: Among adults in the​ country, opinions about federal spending on education and income level are independent.Step-by-step explanation: The null hypothesis (H0) is the statement that two phenomena are unrelated (the response and the income level). This hypothesis indicates that a population parameter (in this case, a parameter that represents association) is equal to a hypothetical value.And the alternative hypothesis is what you expect to prove; that the two phenomena are related in some way. Normally, this hypothesis indicates that a population parameter (in this case, a parameter that represents association) is different from a value.
