Marketing Analyst
A marketing analyst is interested in predicting prospective buyer's knowledge about compact disc players.A random sample of 36 buyers was taken,a questionnaire about compact disc players completed,and information about education,income and age was obtained.In estimating the equation,the variables were:
y = knowledge about compact disc players
x₁ = education (years)
x₂ = age
x₃ = income (thousands of dollars)
The resulting output using MINITAB was: $$\begin{array}{l}\text { The regression equation is }\\\begin{array} { l c c r } Y = 50.2 + 4.36 \times 1 - 0.632 \times 2 - 0.068 \times 3 & \\& & \\\text { Predictor } & \text { Coef } & \text { Stdev } & \text { t-ratio } \\\text { Constant } & 50.168 & 4.977 & 10.08 \\X 1 & 4.3609 & 0.4064 & 10.73 \\X 2 & - 0.63169 & 0.08172 & - 7.73 \\X 3 & - 0.0682 & 0.1176 & - 0.58 \\s = 4.615 & \text { R-sq } = 85.0 \% & \text { R-sq(adj) } = 83.6 \%\end{array}\end{array}$$
