In a sample of 100 VCRs what are the chances that more than 20 need service while under warrantee What are the chances than none need service while still under warrantee b. What proportion of all VCRs of this brand and model will need service within the warrantee period 1 Chapter 1 Overview and Descriptive Statistics 4. a. Concrete All living . Citizens all mutual funds marketed in the . all books published in 1980. Hypothetical All grade point averages for University of California undergraduates during the next academic year. Page lengths for all books published during the next calendar year. Batting averages for all major league players during the next baseball season. b. Concrete Probability In a sample of 5 mutual funds what is the chance that all 5 have rates of return which exceeded 10 last year Statistics If previous year rates-of-return for 5 mutual funds were and can we conclude that the average rate for all funds was below 10 Conceptual Probability In a sample of 10 books to be published next year how likely is it that the average number of pages for the 10 is between 200 and 250 Statistics If the sample average number of pages for 10 books is 227 can we be highly confident that the average for all books is between 200 and 245 5. a. No the relevant conceptual population is all scores of all students who participate in the SI in conjunction with this particular statistics course. b. The advantage to randomly choosin g students to participate in the two groups is that we are more likely to get a sample representative of the population at large. If it .
