Q2: A shopping center developer claims in a presentation to a potential client that at least 40% of the audit female population in a community visit the mall one or more times a week. To test this claim, the developer selected a random sample of 100 households with an adult female present6 and asked if they visit the mall at least one day per week. Thirty-eight of the 100 respondents replied "yes" to the question.
Based on the sample data and a significance level of 0.05, what should be concluded about the developer's claim? Show the decision rule and your analysis clearly?
