Question

An advertising agency wants to test the hypothesis that the proportion of adults in a country who read a sunday magazine is 25 percent. The null hypothesis is that the proportion reading the sunday magazine is: more than 25 % equal to 25% cannot be determined from the info. Given different from 25% less than 25 %

Answer 1

The null hypothesis is that the proportion of reading the Sunday magazine is equal to 25%

option b is the correct answer.

• A hypothesis is an assumption that is a proposed explanation for a particular event. The scientific method requires that a hypothesis be testable in order for it to be considered a scientific hypothesis. Scientists generally base scientific hypotheses on previous observations that cannot be satisfactorily explained by the scientific theories that are currently available.
• A simple hypothesis predicts the relationship between two variables: independent and dependent. These examples show how this relationship works. Drinking sugary drinks on a daily basis contributes to obesity. Cigarette smoking on a daily basis causes lung cancer.
• There are two mutually exclusive hypotheses in hypothesis testing: the Null Hypothesis (H0) and the Alternative Hypothesis (H1). One of these is the claim to be tested, and the claim will either be supported or not based on the sampling results (which infer a similar measurement in the population).
• here the null hypothesis is that the proportion reading the Sunday magazine is equal to 25%
