3. In a study of the relationship of the shape of a tablet to its dissolution time, 6 disk-shaped ibuprofen tablets and 8 oval-shaped ibuprofen tablets were dissolved in water. The dissolve times, in seconds, were as follows: Disk: 269.0 249.3 255.2 252.7 247.0 261.6 Oval: 268.8 260.0 273.5 253.9 278.5 289.4 261.6 280.2 Can you conclude that the mean dissolve times differ between the two shapes?
