A carpentry shop currently sells 66000 decoy ducks per year at a cost of 16 dollars each. In the previous year when they raised the price to 21 dollars, they only sold 51000 decoy ducks that year. Assuming the amount of decoy ducks sold is in a linear relationship with the cost, what price should the carpentry shop charge per decoy duck to maximize their revenue?

One type of roan color in horses is fully dominant over normal solid color and results in the presence of white hairs interspersed among the solid color hairs. The locus for one type of paint in horses (Overo paint) is fully dominant, but when homozygous the Overo allele is lethal. Both loci are autosomal. Two roan and paint horses that are heterozygous for roan and heterozygous for Overo paint were crossed. What is the probability that their first offspring is also a roan and paint horse? Consider only living progeny.

Because of the forces caused by its rotation, Earth is an oblate ellipsoid rather than a sphere. The equatorial radius is 3963 miles and the polar radius is 3950 miles. Find an equation of the ellipsoid. (Assume that the center of Earth is at the origin and that the trace formed by the plane z = 0 corresponds to the equator.)

To determine whether the pipe welds in a nuclear power plant meet specifications, a random sample of welds is selected, and tests are conducted on each weld in the sample. Weld strength is measured as the force required to break the weld. Suppose the specifications state that mean strength of welds should exceed 100 lb/in2; the inspection team decides to test H0: μ = 100 versus Ha: μ > 100. Explain why it might be preferable to use this Ha rather than μ < 100.

In a large Introductory statistics lecture hall, the professor reports that 55% of the students enrolled have never taken a Calculus course, 32% have taken only one semes- ter of Calculus, and the rest have taken two or more semesters of Calculus. The professor randomly assigns students to groups of three to work on a project for the course. What is the probability that the first groupmate you meet has studied some calculus?

Let us suppose that (28 , 32) inches is an 80% one-sample confidence interval for the average height of all adult miniature horses. Some people believe that the population average height is 29.5 inches. Based on the confidence interval, is this a plausible belief? Group of answer choices No, because 29.5 does not belong to the interval. Yes, because 29.5 lies within the interval. Yes, because 29.5 does not belong to the interval. No, because 29.5 lies within the interval.
