In a certain desert region, 15% of the coyotes are super geniuses while 85% are not. Recent records indicate that 70% of the super genius coyotes will never catch a roadrunner while 90% of the coyotes that are not super geniuses will never catch a roadrunner.
b. If a coyote is randomly chosen in this desert region, find the probability that the coyote is not a super genius and will never catch a roadrunner

1. Have hours of amusement pretending to be a rock with the ACME Artificial Rock. “Have Fun, Be Popular, Be A Rock!” From a lot of fifty artificial rocks, four of them are defective while the rest are not. Eight artificial rocks will be selected from this lot at random and sent to eight super genius coyotes to help them catch a roadrunner. a. What is the probability that all eight of the artificial rocks chosen and sent to the...
A random sample of 51 adult coyotes in a region of northern Minnesota showed the average age to be x = 2.03 years, with sample standard deviation s = 0.82 years. However, it is thought that the overall population mean age of coyotes is μ = 1.75. Do the sample data indicate that coyotes in this region of northern Minnesota tend to live longer than the average of 1.75 years? Use α = 0.01. (a) What is the value of...
please answer all 1. (a) A certain species of bird always lays 3 eggs in the spring, but it is not guaranteed that all of the eggs it lays will hatch. Scientists think that a model for the nunber, X, of eggs that hatch has a probability distribution given by 0 where θ is a parameter to be estimated. i) Given that at least one egg hatches, determine the probability that all three eggs in a nest hatch. 2 marks...
