In order to determine if the average bacteria content of southern flowing streams is less than the average bacteria content of northern flowing streams, independent random samples of 28 southern flowing streams and 35 northern flowing streams were taken. Given the testing statistics below, determine if the data provides sufficient evidence to conclude that the average bacteria content of southern flowing streams is less than the average bacteria content of northern flowing streams, at the 5% significance level. H0:μs≥μn Ha:μs<μn t0=−0.108 t0.05=−1.999 Select the correct answer below:   No; the test statistic is less than the critical value.   Yes; the test statistic is greater than the critical value.   No; the test statistic is greater than the critical value.   Yes; the test statistic is less than the critical value.
