1) In a certain town, 60% of adults have a college degree. The accompanying table describes the probability distribution for the number of adults (among 4 randomly selected adults)who have a college degree. Find the variance for the probability distribution.
x P(x)
0 0.0256
1 0.1536
2 0.3456
3 0.3456
4 0.1296
2) An airline estimates that 98% of people booked on their flights actually show up. If the airline books 76 people on a flight for which the maximum number is 74, what is the probability that the number of people who show up will exceed the capacity of the plane?
Use the Poisson Distribution to find the indicated probability.
3) A mountain search and rescue team receives an average of μ = 0.75 calls per day. Find the probability that on a randomly selected day, they will receive fewer than two calls.
Evaluate the area under the standard normal curve that lies to the left of z = - 3.49 and simple random sample of size
Describe what do you mean by conditional probability. Give clinical example to support the explanation.
A recent article suggested that if you earn $25,000 a year today and the inflation rate continues at 3 percent per year, you'll need to make $33,598 in 10 years to have the same buying power. You would need to make $44,771 if the inflation rate ju..
Suppose you take a sample of size 100 of test scores and find that the mean is 63. What is the z-score corresponding to this sample mean?
Modify (change) your sample size to 18600. Construct a new 95% Confidence Interval.
Select a US citizen and a citizen of China at random, independently of one another. Determine the probability that both have type O blood?
Critical Thinking: Discuss the implications of: magnitude (from 0 to 1); sign ( + or -); and probability versus causality for the Correlation Coefficient (also known as the Pearson Product-Moment Correlation Coefficient).
Write an expression for the probability that during a given 1-min period, all of the operators receive exactly the same number of requests.
Age effects in medical care. The type of medical care a patient receives may vary with the age of the patient. A large study of women who had a breast lump investigated whether or not each woman received a mammogram and a biopsy when the lump was ..
Construct a 95% confidence interval for the population mean.
At the 5 percent level of significance, can we conclude that the mean weight is greater than 16 ounces? Determine the p- value.
"Give an example of a statistic that you have heard quoted in the media that you do not believe is accurate either due to bias or other incorrect statistical methods. Describe the relevant population and the source (e.g. newspaper, TV, radio, inte..
