Under normal operating conditions 1.5% of the transistors produced in a factory are defective. An inspector takes a random sample of forty transistors and finds that two are defective. a) What is the probability that exactly two transistors will be defective from a random sample of forty under normal operating conditions? b) What is the probability that more than two transistors will be defective from a random sample of forty if conditions are normal?

Electrical engineers recognize that high neutral current in computer power systems is a potential problem. A survey of computer power system load currents at U.S. sites found that 10% of the sites had high neutral to full-load current ratios (IEEE Transactions on Industry Applications). If a random sample of five computer power systems is selected from a large number of sites in the country, what is the probability that exactly three will have a high neutral to full-current load ratio?
In a survey of U.S. adults with a sample size of 2082, 370 said Franklin Roosevelt was the best president since World War II. Two U.S. adults are selected at random from this sample without replacement. Complete parts (a) through (d). (a) Find the probability that both adults say Franklin Roosevelt was the best president since World War II. The probability that both adults say Franklin Roosevelt was the best president since World War II is O. (Round to three decimal places as needed.) (b) Find the probability that neither adult says Franklin Roosevelt was the best president since World War II. The probability that neither adult says Franklin Roosevelt was the best president since World War II is (Round to three decimal places as needed.) (c) Find the probability that at least one of the two adults says Franklin Roosevelt was the best president since World War II. The probability that at least one of the two adults says Franklin Roosevelt was the best president since World War II is.…
Question 8 8 buses out of a fleet of 20 buses have a manufacturing defect. Given that 5 buses are selected; a) Construct the pmf representing the number of selected defective buses. b) Calculate the expected number of selected defective buses.
Pollsters are concerned about declining levels of cooperation among persons contacted in surveys. A pollster contacts 94 people in the 18-21 age bracket and finds that 80 of them respond and 14 refuse to respond. When 265 people in the 22-29 age bracket are contacted, 241 respond and 24 refuse to respond. Assume that 1 of the 359 people is randomly splected. Find the probability of getting someone in the 22-29 age bracket or someone who refused to respornd. Report the answer as a percent rounded to one decimal place accuracy. You need not enter the "%" symbol. P(22-29 or refused) % %3D (Hint: It might be helpful to organize the data into a table first.)

2. Imagine two houses that are infested with house mice. In House 1, the mice have a frequency of the "curly coat allele" of 0.7. In House 2, the frequency of that allele is 0.4. Each house contains a population of 40 mice. There are regularly 5 migrants from each house to the other every generation. а. What is m for House 1? b. What will the expected frequency of the curly coat allele be in the next generation of House 2? Show your work to the nearest 0.01. С. Is evolution occurring in these populations? How do you know?

1. Power companies severely trim trees growing near their lines to avoid power failures due to falling limbs in storms. Applying a chemical to slow the growth of the trees is cheaper than trimming, but the chemical kills some of the trees. Suppose that one such chemical would kill 20% of sycamore trees. The power company tests the chemical on 250 sycamores. Consider this a SRS from the population of all sycamore trees. Calculate the probability that less than 24% of the tress in the sample are killed. (Hint: Shape, Center, Spread, Curve, Calculations, Conclusion....)

Suppose a group of 900900 smokers (who all wanted to give up smoking) were randomly assigned to receive an antidepressant drug or a placebo for six weeks. Of the 356356 patients who received the antidepressant drug, 113113 were not smoking one year later. Of the 544544 patients who received the placebo, 203203 were not smoking one year later. Given the null hypothesis ?0:(?1−?2)=0H0:(p1−p2)=0 and the alternative hypothesis ??:(?1−?2)≠0H, conduct a test to see if taking an antidepressant drug can help smokers stop smoking. Use ?=0.01(a) The rejection region is |?|>(b) The test statistic is ?=zThe final conclustion is
10. An atom of Uranium-238 is unstable and will eventually decay (i.e., emit a particle and turn into a different element). Given an atom of Uranium-238, the time elapsed until it decays, in years, is modeled as an Exponential random variable with parameter 1 = 0.000000000155. How many years must pass for there to be a 50% chance that the Uranium atom decays?
