About 96 percent of the very largest colleges and universities offer distance learning courses. Suppose you are to randomly select 20 such institutions and count the number (denoted by X) that offer distance learning courses. The value of X depends on the selected random sample of institutions so it would vary from one sample to another. On average, we expect ____ schools with a standard deviation of ______ schools would offer such courses. (Round to 1 decimal place).

(9 points) Education. Post-secondary educational institutions in the United States (trade schools, colleges, universities, etc.) traditionally offer four different types of degrees or certificates. The U.S. Department of Education recorded the highest degree granted by each of these institutions in the year 2003. The percentages are shown in the table below. A random sample of 250 institutions was taken in 2013 and the number of institutions in the sample for each category is also shown in the table. Conduct a...

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. 71.3% of those students replied that, yes, they believe that same-sex couples should have the right to legal marital status. Suppose that you randomly select freshman from the study until you find one who replies "yes." You are interested in the number of freshmen you must ask. What is the probability that you will need to...
