- For 50 randomly selected speed dates, attractiveness ratings by males of their female date partners (x) are recorded along with the attractiveness ratings by females of their male date partners (y); the ratings range from 1 to 10. The 50 paired ratings yield x = 6.4, y = 6.0, r= -0.207, P-value = 0.149, and y=7.38-0.210x. Find the best predicted value of ŷ (attractiveness rating by female of male) for a date in which the attractiveness rating by the male of the female is x=9. Use a 0.05 significance level. The best predicted value of ŷ when x = 9 is (Round to one decimal place as needed.)

Show work. Let Y > 0 be a continuous random variable representing time from regimen start to bone-marrow transplant. Everyone does not survive long enough to get the transplant. Let X > 0 be a continuous random variable representing time from regimen start to death. We can assume X ⊥ Y and model time to death as X ∼ Exp(rate = θ) and time to transplant as Y ∼ Exp(rate = µ). Where Exp(rate = λ) denotes the exponential distribution with density f(z | λ) = λe−λz for z > 0 and 0 elsewhere - with λ > 0. a.) Compute the probability that a patient dies before receiving transplant. b.) Assume that we have θ = 1/10 and µ = 1/15. Use the rexp() function in R for i = 1, 2, . . . , 10000 in simulating death and transplant times for 10,000 patients Xi ∼ Exp(1/10) and Yi ∼ Exp(1/15). What is the proportion of simulated patients who receive transplant before death?

Find the normal equations to the curve 2* = ax + bx + c %3D 2 = ax+ bx + cThe toco toucan, the largest member of the toucan family, possesses the largest beak relative to body size of all birds. This exaggerated feature has received various interpretations, such as being a refined adaptation for feeding. However, the large surface area may also be an important mechanism for radiating heat (and hence cooling the bird) as outdoor temperature increases. Here are data for beak heat loss, as a percent of total body heat loss from all sources, at various temperatures in degrees Celsius.
