From candy to jewelry to flowers, average consumer was expected to spend $123.89 for Mother's Day 2009, according to April 2009 National Retail Federation survey. Local merchants felt this average was too high for their area. They contracted an agency to conduct a study. A random sample of 60 consumers was taken at a local shopping mall the Saturday before Mother's Day and produced a sample mean amount of $106.27. If ? = $39.50, does the sample provide sufficient evidence to support the merchants' claim at the 0.05 level of significance?
