Suppose that 56% of all college seniors have a job prior to graduation. If a random sample of 55 college seniors is taken, approximate the probability that fewerthan 28 have a job prior to graduation. Use the normal approximation to the binomial with a correction for continuity.Round your answer to at least three decimal places. Do not round any intermediate steps.(If necessary, consult a list of formulas.)

DLP projectors are used in the majority of cinema projection systems and require a special light bulb to display a picture. Assume that the average life of a DLP bulb is 2,000 hours and that this failure time follows the exponential distribution. Answer the following questions, performing all computations with Excel functions.
An economist has observed that the time between recessions has an exponential distribution with mean 100 months. Find the probability that the time between recessions will be located in the interval (50, 200) months given that it exceeds 100 months. (Enter your answer to two decimal places. For "0.72", you would write 0.72). Do not round.
Assume that the entire sample has 8 positive observations and 4 negatives observations. Variable X1: at the left branch has 9 positive observations and 3 negatives observations;at the right branch has 8 positive observations and 8 negative observations. What is the information gain or reduction in uncertainty of X1 using the Gini index? (round to two decimal spaces)
Suppose that 12% of the population of the U.S. is left-handed. If a random sample of 190 people from the U.S. is chosen, approximate the probability that at most 24 are left-handed. Use the normal approximation to the binomial with a correction for continuity. Round your answer to at least three decimal places. Do not round any intermediate steps.
Two geysers that are near to each other are labelled as Geyser A and Geyser B. The time between eruptions for a given geyser follows an exponential distribution. The eruption times of the two geysers are independent of one another. The mean amount of time between eruptions of Geyser A is 39 minutes, and the mean amount of time between eruptions of Geyser B is 66 minutes. Given that exactly one of the geysers erupts within the next 49 minutes, determine the probability that it will be Geyser A. O 0.6654 0.7850 O 0.7252 O 0.6953 O 0.7551
Use the exponential distribution to determine the probability of the failure of a vacuum tube component after 2000 hours given that they last on average for 3000 hours. Round your answer to four decimal places.
