Let wages denote a person's hourly wages and edu denote their years of education. Suppose thatwages = ß1 + Bzedu + ß3edu² + eand that e is normally distributed with mean zero and variance one (so e ~ N(0, 1)). Suppose we know B1 = 1, B2 = 0.2, ß3 = -0.01, and we observe an individual with16 years of education. What is the probability that her wages are larger than one? In the options below, Z ~ N(0, 1).O a. P(Z > -0.64)Ob.1- P(Z > 1.64)O c. None of the other options is correct.O d. 1- P(Z > -0.64)O e. P(Z > 1.64)

Let x be a random variable that represents the weights in kilograms (kg) of healthy adult female deer (does) in December in a national park. Then x has a distribution that is approximately normal with mean ? = 62.0 kg and standard deviation ? = 9.0 kg. Suppose a doe that weighs less than 53 kg is considered undernourished. (a) What is the probability that a single doe captured (weighed and released) at random in December is undernourished? (Round your answer to four decimal places.) (b) If the park has about 2400 does, what number do you expect to be undernourished in December? (Round your answer to the nearest whole number.) (c) To estimate the health of the December doe population, park rangers use the rule that the average weight of n = 70 does should be more than 59 kg.
