The poverty level for a family of four, two parents with two children under 18, for selected years from 1990 is shown in the following table. Poverty Threshold for a Family of Four Year 1990 1997 2000 2005 Threshold $14,300 $15,400 $18,800 $20,150 (a) Find the least squares linear regression function for threshold level as a function of years since 1990. (Let x = 0 represent the year 1990. Round your coefficients to one decimal place.) y = (b) Use the linear function to estimate when the poverty threshold level will reach $27,000. (Round your answer down to the nearest year.) The threshold level is estimated to reach $27,000 in the year 2016
The table shows the national expenditures for health care in billions, in a country for the selected years from 1990 to 2020.

The following is a 7-month-demand-history for a certain product. Assuming that linear trend appears, develop the equation of regression line. Round values of coefficients to two decimal places. Use the equation to prepare a forecast for December 2004.
The total number of views a certain video has on a social media website is recorded every day for five days. The results are recorded in the table below. Day 0 1 2 3 4 5 Total Views 2018 4575 14,724 39,019 93,130 317,352 a) Determine an exponential regression of the form y = ab using the least-squares method to fit this data, where y is the total number of views the video has on day x. Round each value to four decimal places. b) Using the regression from a), how many views will the video have at the end of day 7 ? Round to the nearest whole number.
The following data gives the approximate population of the world for selected years from 1850 until2000. Year 1850 1900 1950 1980 2000 Population 1.3 (billions) 1.6 3 4.4 Assume that the population growth can be modeled with an exponential function p = bemx where x is the year and p is the population in billions. Use linearleast-squares regression to determine the constants b and m for which the function best fits the data. Use the equation to estimate the population in the year 1970.
