Choose the number sentence that illustrates the distributive property of multiplication over addition. 3 × (7 + 2) = (3 + 7) × (3 + 2)

3 × (7 + 2) = (3 × 7) + 2

3 × (7 + 2) = (3 × 7) + (3 × 2)

Recall that the owner of a local health food store recently started a new ad campaign to attract more business and wants to know if average daily sales have increased. historically average daily sales were approximately $2,700. the upper bound of the 95% range of likely sample means for this one-sided test is approximately $2,843.44. if the owner took a random sample of forty-five days and found that daily average sales were now $2,984, what can she conclude at the 95% confidence level?
