An article reports that the average initial rate of absorption (in g/min·cm2) for a sample of five clay bricks with fine glass particles added was 1299.8 with a standard deviation of 329.8, and the average for another sample of fifteen bricks without glass particles added was 4500.8 with a standard deviation of 271.6. Let μXμX represent the population mean without glass particles and let μYμY represent the population mean with glass particles. Find a 98% confidence interval for the difference μX−μYμX−μY. Round down the degrees of freedom to the nearest integer and round the answers to three decimal places.

An article reports an investigation into the toxicity of bilirubin on several cell lines. Ten sets of human liver cells and 25 sets of mouse fibroblast cells were placed into solutions of bilirubin in albumin with a 1.4 bilirubin/albumin molar ratio for 24 hours. In the 10 sets of human liver cells, the average percentage of cells surviving was 53.9 with a standard deviation of 10.7. In the 25 sets of mouse fibroblast cells, the average percentage of cells surviving...

A tire manufacturer is interested in testing the fuel economy for two different tread patterns. Tires of each tread type are driven for 1000 miles on each of 18 different cars. In a separate experiment, 18 cars were outfitted with tires with tread type A, and another 18 were outfitted with tires with tread type B. Each car was driven 1000 miles. The cars with tread type A averaged 23.94 mpg, with a standard deviation of 1.79 mpg. The cars...

A computer system administrator notices that computers running a particular operating system seem to freeze up more often as the installation of the operating system ages. She measures the time (in minutes) before freeze-up for seven computers one month after installation, and for nine computers seven months after installation. The results are as follows: One month after install:      207.4    233.1    215.9    235.1    225.6    244.4    245.3 Seven months after install: 84.3      53.2      127.3    201.3    174.2    246.2    149.4    156.4    104.3 Let μXμX...
