A marketing researcher tested whether the amount older customers spend eating at restaurants per month differs from the amount younger customers spend eating at restaurants per month on average. The researcher assumed equal population variances and selected a random sample of 56 older customers and a random sample of 56 younger customers. If the level of significance equals 0.05 and the calculated value for the associated test statistic equals -1.8342, did the researcher conclude that the amount older customers spend eating at restaurants per month differs from the amount younger customers spend eating at restaurants per month, on average?
