Problem 122Multiple Choice
Based on a market study, we want to know if adults aged and over are more likely to buy a product labeled 'Organic' compared to adults in general. In the age group, out of respondents indicated they were more likely, while out of total respondents expressed the same likelihood. Does the proportion of adults aged and over who are more likely to buy an 'Organic' product significantly differ from the proportion in the general adult population?
