A new drug designed for treatment of hormone secretion problems is tested on laboratory rats with hormone secretion problems. The scientists are concerned that although many of the secretion problems were solved using the drug, there is an undesirable additional outcome of the weight of the laboratory rats changing after the new drug is tested on them. The weights before the treatment are believed to be Normally distributed with mean [41 . The weights after the treatment are also believed to be Normally distributed but with a possibly dierent mean #2. We wish to estimate the difference [42 m . A random sample of the weights of 100 rats before the treatment was obtained, and the mean of these 100 weights was 521 = 504.5 g, while the standard deviation was s1 = 100 g. A random sample of the weights of 30 different rats after the treatment was also obtained, and the mean of these 30 weights was i2 = 539.1 g, while the standard deviation was .32 = 90 grams. Find the 95% condence interval for M2 m. To avoid the complicated formula for the df, use the conservative rule for the dfas the smaller of H1 1 and n2 1.
