5. Suppose that annual precipitation is uniformly distributed, and ranges between 25 inches and 72 inches. (a) What is the probability that a year will have between 29 and 44 inches of precipitation? (2) (b) What is the 30th percentile of this distribution? (2) 6. Wheat yields per acre are normally distributed, with mean 46 bushels, and standard deviation 10 bushels. (a) What is the probability that next year’s yield is between 35 and 50 bushels? (2) (b) What is...
A random sample of 100 US cities yields a 90% confidence interval for the average annual precipitation in the US of 33 inches to 39 inches. Which of the following is false based on this interval? The margin of error is 3 inches. O 90% of random samples of size 100 will have sample means between 33 and 39 inches. O We are 90% confident that the average annual precipitation in the US is between 33 and 39 inches. O...
A researcher tells you that flights between two cities in the United States are uniformly distributed with arrival times that vary between 4 hours and 4 hours30 minutes, with a mean of 4 hours 15 minutes. Sketch out a related graph, being sure to label the base and the height appropriately. What is the probability of a randomly chosen flight between these two cities arriving in less than4 hours 10 minutes? What is the probability of a randomly chosen flight...
The distance between two cities is 100 mi. Is the number of kilometers between the two cities larger, smaller, or equal to 100? a) equal to 100 b) smaller than 100 c) larger than 100
A bus travels between two cities A and B which are 100 miles apart. If the bus has a breakdown, the distance from the breakdown to city A has a uniform distribution over (0,100). There is a bus service station located 40 miles from A (between A and B) Find the expected distance from the breakdown location to the service station.
The 70-year long-term record for weather shows that for New York State, the annual precipitation has a mean of 39.63 inches and a standard leviation of 4.56 inches. The annual precipitation amount has a normal distribution. (Give your answers correct to four decimal places.) (a) What is the probability that next year the total precipitation for New York State is more than 50.6 inches? 0.9919 x (b) What is the probability that next year the total precipitation for New York...
Q2) To reduce travel time between two cities such as San Francisco and Los Angeles, engineers have proposed building a rail tunnel along a straight line connecting the cities. A train, its d unpropelled by any engine and starting from rest, would fall through the first half of the tunnel and then 10 move up the second half. The technical challenges are immense (the tunnel would need to evacuated) but it is an interesting system to consider. Assuming Earth to...
