    **Means**
    - Mean ad_spend: 6150 / 8 = 768.75
    - Mean signups: 434 / 8 = 54.25
    
    **Sums of deviations**
    - Σ(dx·dy) = 23,912.5
    - Σ(dx²) = 624,687.5
    - Σ(dy²) = 971.5
    
    **Pearson r**
    
    r = 23,912.5 / √(624,687.5 × 971.5)
    = 23,912.5 / √606,883,906.25
    = 23,912.5 / 24,635.01
