You may need to use the appropriate technology to answer this question. Consider the following data on price ($) and the overall score for six stereo headphones tested by a certain magazine. The overall score is based on sound quality and effectiveness of ambient noise reduction. Scores range from 0 (lowest) to 100 (highest). Brand A B C D E F | O Ho: Bo= 0 Ha: Bo #0 ⒸH₁: B₁ = 0 Ha: B₁ * 0 O Ho: B₁ ≥ 0 H₂: B₁ <0 Price ($) Ho: B₁ * 0 H₂: B₁ = 0 180 150 95 70 70 35 Score 74 69 59 56 (a) The estimated regression equation for this data is ý = 23.397993 +0.306020x, where x = price ($) and y = overall score.
