The Higher Education Research Institute at UCLA collected data from 203,967 incoming first-time, full-time freshmen from 270 four-year colleges and universities in the U.S. 71.8% of those students replied that, yes, they believe that same-sex couples should have the right to legal marital status. Suppose that you randomly pick eight first-time, full-time freshmen from the survey. You are interested in the number that believes that same-sex couples should have the right to legal marital status. Construct the probability distribution function...

Structural steel is often treated with a protective coating (called an intumescent coating) that insulates the steel against damage from fire
1. The sampling distribution of the sample mean Structural steel is often treated with a protective coating (called an intumescent coating) that insulates the steel against damage from fire. Coatings are rated according to the number of hours of high-temperature exposure the treated steel can withstand, but if the coating is not applied with a mean thickness within the range specified by its manufacturer, the protection it provides will last for a shorter time than its rating. An office tower under construction...
