Question Suppose that the person in the next cube says to you “We have a really strong theory that the relationship between Y and X in the population is positive, but I just computed the slope from my sample data and it is negative. That’s impossible. There must be a mistake!” Comment on whether this is impossible and why or why not. a.This is impossible since the relationship in the population must exist in the sample.b.This is possible since the relationship in the population does not necessarily exist in the sample.c.None of the above.d.This is impossible since the relationship in the sample must exist in the population.

## Earlier this week you were asked to take a survey and state weather

Question Earlier this week you were asked to take a survey and state weather or not you work full-time while also attending school. According to the community college research center at Columbia University, about 80% of community college students nationally work full time. We want to know if the percentage at Lansing Community College is statistically different than this national percentage. To complete this we will run a hypothesis test at a 0.05 level of significance. The results of our survey indicate that 43.8% of our statistics class works full time. A. Is it more appropriate to run 1-propZtest or a 2-propZtest in this instance? Why?B. State the null and alternative hypothesis.C. Run the hypothesis test using your calculator and state both the test-statistic and the p-value.D. What is the test decision and the conclusion in context drawn from the hypothesis test at a 0.05 significance level?E. What problems might be running this hypothesis test. For example, do we satisfy CLT? Are there any problems with using our class as a sample? Answer below using complete sentences.
