A 1.25 in. by 3.5 in. a rectangular steel bar is used as a diagonal tension member in a bridge truss. The diagonal member is 20 ft long, and its modulus of elasticity is 35,000,000 psi. If the strain in the diagonal member is measured as 0.001200 in./in., determine:
A: The axial stress (precision of 1,000)
B: The tension force in the bar (precision of 10,000)
C: The elongation of the member (precision of 0.00)

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?
