Suppose that a banker claims that her average weekly sales are at least $15,000. A sample of 35 random weeks yields a sample mean of $13,750, with a sample standard deviation of $2,545. Test her claim at the a=0.05 significance level. Set up the null hypothesis H0, and the alternative hypothesis H1. H0: (µ, s,or p),( ?,=,=,<, or =), ($39,367, $7,548, $42,000, 0.05, 35) H1: (µ, s,or p),( ?,=,=,<, or =), ($39,367, $7,548, $42,000, 0.05, 35) Solution H0: < 15,000. HA: >= 15,000.
