Isle Royale, an island in Lake Superior, has provided an important study site of wolves and their prey. Of special interest is the study of the number of moose killed by wolves. In the period from 1958 to 1974, there were 296 moose deaths identified as wolf kills. The age distribution of the kills is as follows. Age of Moose in Years Number Killed by Wolves Calf (0.5 yr)1-56-1011-1516-20 1105074575 Consider all ages in a class equal to the class midpoint. Find the expected age of a moose killed by a wolf and the standard deviation of the ages. (Round your answers to two decimal places.)
Your hypothesis test for a mean with n = 18 has a two-tailed critical region. The test statistic is tt = -1.38. Find the p-value accurate to 2 decimal places.
The Poisson distribution gives the probability for the number of occurrences for a "rare" event. Now, let x be a random variable that represents the waiting time between rare events. Using some mathematics, it can be shown that x has an exponential distribution. Let x > 0 be a random variable and let ? > 0 be a constant. Then y = 1/B e^-x/b is a curve representing the exponential distribution. Areas under this curve give us exponential (refer to screenshot) (a) less than 20 days (i.e., 0 ≤ x < 20) (Round your answer to four decimal places.) (b) more than 50 days (i.e., 50 < x < ∞) Hint: e−∞ = 0 (Round your answer to four decimal places.) (c) between 30 and 70 days (Round your answer to four decimal places.)
Central Limit Theorem with Mean: Suppose a batch of metal shafts produced in a manufacturing company have a variance of 6.25 and a mean diameter of 206 inches. If 90 shafts are sampled at random from the batch, what is the probability that the mean diameter of the sample shafts would differ from the population mean by less than 0.3 inches? Round your answer to four decimal places.
