- New Situation: Many meteorologists track named storms, particularly those that have the potential to make landfall; some meteorologists are more successful in predicting the track of the storm than others. Suppose all currently employed meteorologists are identified as either being employed by the U.S. National Weather Service, employed by a local television station within the United States, or employed in a country other than the United States. In this scenario, what is the population of interest?Part 1 of 4 Does the length of a surgery patient's stay in the hospital depend on the length of time the operation took? The table below gives the operative time (in hours) and the length of the hospital stay (in days) for 10 patients. (Comma separated lists of the data are also provided below the table to ease in copying the data to R.) Operative Time (x) Length of Hospital Stay (y) 5 13 13 12 12 14 17 4 12 3 12 7 15 3 x: 5, 5, 5, 2, 6, 5, 4, 3, 7, 3 y: 13, 13, 12, 12, 14, 17, 12, 12, 15, 7 Conduct a hypothesis test with a 5% level of significance to determine whether or not the operative time and the length of a patient's hospital stay are correlated.

The university administration always thought that the number of applications received was independent of tuition; however, drops in applications and enrollments the past 2 years have proved this theory to be wrong. University admissions officials have developed the following relationships between the number of applicants who accept admission and enter State and the cost of tuition per semester (in-state) (out-of-state) The university would like to develop a planning model that will indicate the in-state and out-of-state tuitions, as well as the number of students that could be expected to enroll in the freshman class.

- F1.6 Question 18 please write on paperTake a moment to address the following scenario. Imagine that two women of similar sociocultural back-grounds, a 21-year-old and a 60-year-old, both express their desired goals as “I want to lose 20 pounds [9 kg] in the next three months.” What thoughts come to mind? What questions would you want to ask of each woman? What motiva-tions might you assume? The one variable presented here is age. What are the assumptions you have about age and weight loss? Our assumptions are that given the aging process and the phases of human development, weight loss might mean different things to these two women. These meanings, along with the women’s personalities, will color their engagement in and approach to coach-ing as they seek to achieve the same goal. REFLECTION 4.12 Lin has learned so many things through coaching. She is now at a place where she has met her initial goals and seems on her way to pursuing her dreams.
