Hello could you explain the steps to solve these. Thank you. (you can use line regression method to show line of best fit)

OD Draw a scatter plot for the data below. If we wanted to know when the population would reach 15,000, would the answer involve interpolation or extrapolation? Justify your reasoning. Year 2000 2005 2010 2015 2020 Population 11,500 12,100 12,700 13,000 13,750 Sketch a line of best fit for the plotted data. Then write the equation of the line and use the equation to estimate f(12). 2. 3. 12 10- 10- 8- 8- 6- 4- 4- 2- 2- 0- 6 8 10 6 10 a) Line of best fit a) Line of best fit b) f(12) b) f(12)4. The table below shows the year and the number of people unemployed in Big City for several years. Create a scatter plot of the data. Determine whether the trend appears linear. If so, use linear regression to calculate the line of best t to two decimal places. Assuming the trend continues, between what two years will the number of unemployed reach 0 people? -!- Number 628 620 564 Unem :10 ed 5. The population of Big City has The following ordered pairs show the population and the year (population, year) for specic recorded years: (2500, 2000], (2665, 2001], (3100, 2003), (3650, 2006), (4255, 2010) increased steadily over a ten-year span. a) Use linear regression to determine a function y, where the year depends on the population. Round to three decimal places. b} Assuming the trend continues, predict when the population will hit 8500
