Clinical literature reports that the duration of a typical cold is roughly 18 days. researchers wanted to know if people tend to underestimate the duration of a typical cold, on average. they surveyed a random sample of 352 healthy adults in georgia and asked them how long they think that a typical cold lasts. the researchers reported a 95% confidence interval of 6.9 to 8.2 days for the mean expected duration of typical cold. the researchers reported that the answers to this question were strongly right-skewed. the 95% confidence interval (6.9, 8.2) they obtained is

To find the extreme values of a function f(x.y) on a curve x-x(t), y y(t), treat f as a function of the single variable t and use the chain rule to find where df/dt is zero. in any other single-variable case, the extreme values of f are then found among the values at the critical points (points where df/dt is zero or fails to exist), and endpoints of the parameter domain. find the absolute maximum and minimum values of the following function on the given curves. use the parametric equations x=2cos t, y 2 sin t functions: curves: i) the semicircle x4,y20 i) the quarter circle x2+y-4, x20, y20 b, g(x,y)=xy
