Q #1

In this problem, we explore the effect on the mean, median, and mode of multiplying each data value by the same number. Consider the following data set. 6, 6, 7, 10, 14 LO USE SALT (a) Compute the mode, median, and mean. mode 6 median 7 mean 13.6 X (b) Multiply each data value by 6. Compute the mode, median, and mean. mode 9 X median 10 X mean 6 X(d) Suppose you have information about average heights of a random sample of airline passengers. The mode is 68 inches, the median is 71 inches, and the mean is 72 inches. To convert the data into centimeters, multiply each data value by 2.54. What are the values of the mode, median, and mean in centimeters? (Enter your answers to two decimal places.) mode 157.54 x cm med... :cm mean Z... Need Help? The Grand Canyon and the Colorado River are beautiful, rugged, and sometimes dangerous. Thomas Myers is a physician at the park clinic in Grand Canyon Village. Dr. Myers has recorded (for a 5-year period) the number of visitor injuries at different landing points for commercial boat trips down the Colorado River in both the Upper and Lower Grand Canyon (Source: Fatefuf Journey by Myers, Becker, Stevens).

MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER At General Hospital, nurses are given performance evaluations to determine eligibility for merit pay raises. The supervisor rates the nurses on a scale of 1 to 10 (10 being the highest rating) for several activities: promptness, record keeping, appearance, and bedside manner with patients. Then an average is determined by giving a weight of 1 for promptness, 3 for record keeping, 4 for appearance, and 2 for bedside manner with patients. What is the average rating for a nurse with ratings of4 for promptness, 6 for record keeping, Z for appearance, and 10 for bedside manner? (Enter your answer to one decimal place.) Z Need Help? Where does all the water go? According to the Environmental Protection Agency (EPA), in a typical wetland environment, 35% of the water is outflow; 48% is seepage; 8% evaporates; and 9% remains as water volume in the ecosystem (Reference: United States Environmental Protection Agency Case Studies Report 832-R93005). Chloride compounds as residuals from residential areas are a problem for wetlands. Suppose that in a particular wetland environment the following concentrations (mg/I) of chloride compounds were found: outow, 58.7; seepage, 74.2; remaining due to evaporation, 48.5; in the water volume, 43.4. (a) Compute the weighted average of chlorine compound concentration (mg/l) for this ecological system. (Round your answer to one decimal place.) E men
