A synthetic fiber used in manufacturing carpet has tensile strength that is normally distributed with mean 75.5 psi and standard deviation 3.5 psi. Find the probability that a random sample of n = 6 fiber specimens will have sample mean tensile strength that exceeds 75.75 psi.

In this exercise, use the integration capabilities of a graphing utility to approximate the work done by a press in a manufacturing process. A model for the variable force $F$ (in pounds) and the distance $x$ (in feet) the press moves is given.

Elizabeth is designing another backyard pond design for her company. She follows the same procedure to find the area. She first creates an x by y rectangle to frame her pond diagram. She generates 10,000 random points inside the rectangle and p points land inside the pond. Express the area of the pond algebraically.

Are good grades in high school associated with family togetherness? A Simple Random Sample of 142 highschool students was asked how many meals per week their families ate together. Their responses produced a mean of 3.78 meals per week, with a standard deviation of 2.2. Researchers then matched these responses against the students' grade point averages. The scatterplot appeared to be reasonably linear, so they went ahead with the regression analysis, as seen below. No apparent pattern emerged in the residuals plot.

Dependent variable is GPA
