Each year from 1974 to 1990 the Gallup Polling Organization asked how happy people were in their marriage. The percentage of people that said “very happy” was plotted over time. Use the summary statistics below to compute the least squares regression line to predict the percent of those that are “very happy” based on the year. a) y = 759.0 - 0.3502x b) y = 2098 - 11.79x c) y = -629.3 - 0.3502x d) y = 1866 - 1.790x

Question

Each year from 1974 to 1990 the Gallup Polling Organization asked how happy people were in their marriage. The percentage of people that said “very happy” was plotted over time. Use the summary statistics below to compute the least squares regression line to predict the percent of those that are “very happy” based on the year.

a) y = 759.0 - 0.3502x

b) y = 2098 - 11.79x

c) y = -629.3 - 0.3502x

d) y = 1866 - 1.790x

x=1982.1 y = 64.845 S₂ = 5.47 $x S₁₂=2.419 r=-0.792
Transcribed Image Text:x=1982.1 y = 64.845 S₂ = 5.47 $x S₁₂=2.419 r=-0.792
