d. Predict the amount of new solar power that will be installed in 2013. Do you have much faith in your prediction? Explain, Round to the nearest tenth as needed.) O A. It is predicted that megawatts of new solar power will be installed in 2013. Since the model fits the data points, it is reasonable to assume that this value will be relatively accurate. OB. It is predicted that relatively accurate. megawatts of new solar power will be installed in 2018. Since 2013 is inside the domain of the given data, it is reasonable to assume that this value will be OC. It is predicted that megawatts of new solar power will be installed in 2013. Since the model does not fit the data points, there should be little or no faith placed in the accuracy of this value.

Section 2.1, question 9
Age is a variable that is important in most if not all epidemiological studies of health because our health is so strongly related to age. The following table is a two-dimensional table that summarizes the distribution of age in a certain population every five years starting with 1970 (the first row) to 2000 (the last row). Each row contains information for one year. Reading across the row (over the column), the table shows the number of individuals in each age group. If you choose this option, please do the following: (a) using the data provided, produce a new two-dimensional table that shows, for each year, the percentage of that year’s total population in each age interval (Tip! In each row, the sum of your percentages should be 100%); and (b) write a brief report (a paragraph or so, no more!) on what these summaries suggest regarding the possibility (or lack thereof) of changes over time in the age distribution of this population. Interval of Age, years…
