In an experiment measuring the rate of absorption (in g/min-cm2) two samples were obtained. For a sample of 9 clay bricks with fine glass particles added, the sample mean was 1299.3 with a sample standard deviation of 329.5.  For a sample of 9 clay bricks without added glass particles, the sample mean was 4500.3 with a sample standard deviation of 271.4. The population variances of each group are assumed to be equal. To construct a confidence interval (under normal regularity conditions) of the difference of the two means, a critical value from which distribution would be used in the calculation?

 When a vessel is damaged, chemicals are released from the vessel walls that attract platelets to the site of the damage. As they accumulate, more chemicals that attract more platelets to the area until the bleeding stops. This represents ________ feedback, with the platelets acting as the ________.
