Consider the following data on price ($) and the overall score for six stereo headphones tested by a certain magazine. The overall score is based on sound quality and effectiveness of ambient noise reduction. Scores range from 0 (lowest) to 100 (highest). Brand Price ($) A B с D E F 180 150 95 70 70 35 Score 76 69 59 56 40 24 (a) The estimated regression equation for this data is ŷ = 21.926421 +0.320736x, where x = price ($) and y = overall score. Does the t test indicate significant relationship between price and the overall score? Use a = 0.05. State the null and alternative hypotheses. ⒸHo: P₁ = 0 H. B. Q
