35 POINTS PLEASE HELP ASAP 1. The table shows the minimum wage rates for the United States during different years.

Year 1978 1979 1980 1990 1991 1996 1997 2007 2008 2009
Minimum hourly wage ($) 2.65 2.90 3.35 3.80 4.25 4.75 5.15 5.85 6.55 7.25

(a) Write the least squares regression equation that models the data. Let x = time in years since 1900 and let y = minimum hourly wage.
(b) Use the equation to estimate the minimum hourly wage of a U. S. worker in 2025. Show your work.

idk what kind of work is this

Step-by-step explanation:

Regression equation = y = 0.1484x + 2.65

4.37

Step-by-step explanation:

Given the data:

Year :

1978 1979 1980 1990 1991 1996 1997 2007 2008 2009

Minimum hourly wage ($) (Y) :

2.65, 2.90, 3.35, 3.80, 4.25, 4.75, 5.15, 5.85, 6.55, 7.25

x = time in years since 1900 and

y = minimum hourly wage

y = mx + c

Slope = m

m = (y2 - y1) / (x2 - x1)

m = (7.25 - 2.65) / (2009 - 1978)

m = 4.6 / 31

m = 0.1484

Intercept c,

y = 2.65, x = 1978 = 0

2.65 = 0.1484(0) + c

2.65 = 0 + c

2.65 - 0 = c

c = 2.65

Hence. The regression equation goes thus :

y = 0.1484x - 2.65

Minimum hourly wage if a U. S worker in 2025

x = 2025 - 1978 = 47 years

y = 0.1494(47) + 2.65

y = 7.0128 - 2.65

y = 4.3718

y = 4.37
