Question:
The table shows the overall scores and the prices per gallon for seven randomly selected interior paints. The overall score represents hiding, surface smoothness, and resistance to staining, scrubbing, gloss change, sticking, mildew, and fading. At \(\alpha=0.10\), can you conclude that there is a significant correlation between the overall score and the price?
