Question: A survey performed by Simmons Market Research investigated the percentage of individuals in various age groups who indicated they were willing to pay more for environmentally friendly products. The results were presented in USA Today "Snapshots." The survey had approximately 3,240 respondents in each age group. Results of the survey follow:
Age Group 18-24 25-34 35-44 45-54 55-64 65 and over
Percentage 11 17 19 20 14 19
Conduct a goodness-of-fit test analysis to determine if the proportions of individuals willing to pay more for environmentally friendly products in the various age groups are equal. Use a significance level of 0.01.
