Proving the converse of the pythagorean theorem means proving that if the                of the squares of the lengths of the                sides of a triangle equals the square of the length of the                        side, then the triangle is a right triangle. shorter longest sum product square similar congruent

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?
