The Carbondale Hospital is considering the purchase of a new ambulance.The decision will rest partly on the anticipated mileage to be driven next year.The miles driven during the past 5 years are as follows:YearMileage13,00024,00033,40043,80053,750a) Using a 2-year moving average, the forecast for year 6 = 3775 miles(round your response to the nearest whole number).b) If a 2-year moving average is used to make the forecast, the MAD basedon this = 116.67 miles (round your response to one decimal place). (Hint:You will have only 3 years of matched data.)c) The forecast for year 6 using a weighted 2-year moving average withweights of 0.40 and 0.60 (the weight of 0.60 is for the most recent period) =3770 miles (round your response to the nearest whole number).The MAD for the forecast developed using a weighted 2-year moving averagewith weights of 0.40 and 0.60= miles (round your response to onedecimal place). (Hint: You will have only 3 years of matched data.)

The question is about forecasting.Given :

C8. According to the Pew Research Center (2015), recent immigrants are better educated than earlier immigrants to the United States. The change was attributed to the availability of better education in each region or country of origin. The percentage of immigrants 25 years of age and older who completed at least high school is reported in this table for 1970 to 2013. Write a statement describing the change over time in the percentage who completed at least a high school degree. 1970 1980 1990 2000 2013 Mexico 14 17 26 30 48 Other Central/South America 57 53 60 66 Asia 75 72 75 82 84 48 68 81 87 95 Europe 36 48 52 58 72 Caribbean 81 91 88 85 85 Africa Source: Pew Research Center, Modern Immigration Wave Brings 59 Million to U.S., Driving Population Growth and Change Through 2065, 2015.

A poll uses responses everal questions to calculate a "Happiness" index that measures overall happiness. An article included the happiness index for the 7 years between 2008 and 2016. Also included in the article were the percentages of people who responded "somewhat agree" or "strongly agree" to the following statements. Statement 1 (happy with life) 1: At this time, I'm generally happy with my life. Statement Year 2008 2009 2010 2011 2013 2015 2016 2 (won't benefit): I won't get much benefit from the things that I do anytime soon.

The numbers of polio cases in the world are shown in the table for various years. Year Number of Polio Cases (thousands) 1988 1992 1996 2000 2005 2007 350 138 33 3 3.2 1.3 Let f(t) be the number of polio cases (in thousands) t years after 1980. Copy the data to Desmos to draw a scatterplot of the data. Make sure to adjust the years so they represent years after 1980. a) Is it better to model the data with a linear or with an exponential model? [Select an answer b) Use regression in Desmos to find an appropriate model for f. Make sure to check Log mode in the parameter window in Desmos if you are fitting an exponential model. f(t) Round the coefficients to 4 decimal places. Hint: Use the variablet from the drop down menu when entering the equation. Do not just type in t. c) Predict the number of polio cases in 2013. d) Find the approximate half-life of the number of polio cases. Round the answer to one decimal place. years
