The tiny zebra and quagga mussels have invaded at least 600 bodies of water in the United States and are causing many problems. These mollusks disrupt the natural food chain, clog pipes, cling to machinery, and foul waterdelivery systems. Independent random samples of quagga mussels were obtained from Lake Texoma and Lake Mead. The size of each mussel (in cm} was carefully measured. The resulting summary statistics are given in the table below. Lake Sample Size Sample Mean Sample Variance I . Texcma I 7 2.188 (1MB 2. Mead l5 |.738 0.258 Is there any evidence to suggest that the population mean size of quagga mussels is larger in Lake Texoma than in Lake Mead? Assume the underlying distributions are normal with equal population variances. Calculate a 95% condence interval to estimate the true dierence in means. in #1.
