A random sample of 31 couples in America showed that they spent an average of $20,000 on their weddings, with a sample standard deviation of $6,000. Based on this study, a researcher claims that the population of couples in America spend an average of less than $32,000 on weddings. Is there enough evidence to support this claim? Test at the 1% significance level using the rejection region method.
