1. ESP: For several years, the U.S. General Social Survey asked subjects, "How often have you felt as though you were felt you were in touch with or connected with someone when they were far away from you?" Of 5,674 sampled subjects who had an opinion, 2,333 said never and the rest said at least once. a. Describe the population of interest. b. Calculate the descriptive statistics (sample proportions) rounding to three decimal places. c. What is the population parameter we want to draw conclusions about (make an inference about)? 2. Use critical thinking to develop an alternative conclusion. A study shows that the number of reported sexually transmitted diseases was significantly higher for high schools that offered courses in sex education than for high schools that did not. Conclusion: The introduction of sex education courses at the high school level is directly correlated to increased promiscuity among teens. 3. An engineer is designing a machine to manufacture mechanic's gloves and she obtains the following sample of hand lengths (mm) of randomly selected adult males based on data gathered: 193 189 212 150 196 195 220 232 a. Define this data set as discrete or continuous and explain why. b. Hand lengths are what level of measurement? c. Compare the mean and median for this data set and if you can draw any conclusions from these values. 4. Define both stratified and cluster sampling. What are the similarities and differences between the two methods? Which design do you think is used more frequently in practice and why?
