Suppose that fund-raisers at a university call recent graduates to request donations for campus outreach programs. They report the following information for last year's graduates. Size of donation Proportion of calls 0.40 $0 0.30 0.25 Three attempts were made to contact each graduate. A donation of $0 was recorded both for those who were contacted but declined to make a donation and for those who were not reached in three attempts. Consider the variable x = amount of donation for a person selected at random from the population of last year's graduates of this university. (a) Write a few sentences describing what donation amounts you would expect to see if the value of x was observed for each of 1,000 graduates. to donate $25, and roughly $10 $25 $50 (c) What is P(x ≥ 25)? You would expect roughly of the graduates to donate nothing, roughly frequencies would be close to, but not exactly, these values. The four frequencies would add to (d) What is P(x > 0)? 0.05 (b) What is the most…
Suppose a weather report indicates that the probability of rain this week is 0.20. According to the report, if it rains this week, then the probability of rain next week is 0.32. If it does not rain this week, then the probability of rain next week is 0.13. The tree diagram models this weather report. Determine the probability that it will not rain for the next two weeks. Express your answer as a decimal precise to two decimal places.

Carl Catcher has a batting average of .370, meaning that he makes a hit 37% of the times he is up at bat. Pete Pitcher has a batting averager of only .110. Let x be the number of times Carol comes up to bat and let y be the number of times Pete comes to bat. a. If Carl bats 7 times and Pete bats 3 times, what should ther overall batting average be? b. If a total of 50 times at bat, how many times may Pete bat in order for their combined average to be as close as possible to .300? (define 3 variables, write system and solve)

One night on a cold street in Copenhagen, a drunk walked by staggering left and right. Every 1 minute, the drunk changes direction and walks xmeters to the left, or y meters to the right. The probability that the drunkard walks to the left is p (ie probability of walking right = 1-p).The drunk started walking from a bar where 200 meters to the left was a garden; and 200 meters to the right is the police station.A. Predict which way the drunkard is walking? Elaborate why drunkenness walk towards the park or the police station!B. Count how many meters is the drunkard's location after walking n minutes!C. If the drunk is about to fall asleep after walking for 1 hour, find out where the drunk is Sleep? has it passed the park/police station? Note: Take the last 3 digits of my ID. Use the steps below: 1. For example, ID 2602296545 → then what is taken is 545. 2. Change the number 0 to number 1; example: ID 545 → 145 3. From the new ID, take the largest and smallest digits; example: min…
