Your professor has a vehicle with halogen headlight bulbs (advanced technology when introduced in 1962). He is disappointed that the headlights in his car not as bright as the HID headlights in his wife's Lexus. There are 3'd party manufacturers of high intensity halogen replacement bulbs that are said to be 30-50% brighter than standard halogen

Consider a continuous random variable X whose probability densityr [1 if a: {i 0 function is as follows: _f(:r:) = get: if 0 g I E 2 0 if a: :3- 2. (a) Find Pr(X E 1) .

Estimation Evaluation Criterion: In order to evaluate your estimation or prediction, we also generated 200 random realizations of Y's for each combination of (X1, X2) in the testing data set. However, we will not release these 200 independent realizations for the testing data. Instead we will use them to compute a baseline estimation of Abase(X1,

Your team has observed that over the last several years, the dynamics of the depth of ice in the Columbia Ice Field has on average followed the discrete time dynamical system (DTDS) given by xt+1=0.9xt+3xt+1=0.9xt+3 where time tt is measured in years, xtxt represents the depth in metres at the beginning of year tt, 0.90.9 represents the fraction

Question 5 (1 point) Most people think normal body temperature is 98.6 .F. In 1992, the Journal of the American Medical Associationasserted that a more accurate figure may be 98.2 F on average, and that body temperatures had a standard deviation of 0.7 F. Assuming this is true and body temperatures follow a normal distribution, what is the
