The parameters are: - x is the number of successes. An airline claims that 72% of all its flights to a certain region arrive on time. B. Sam will make 4 flights in the next two weeks. An airline claims that there is a 0.10 probability and statistics. The probability is: In which: Then: 0. Thus the proportion of times a three is observed in a large number of tosses is expected to be close to 1/6 or Suppose a die is rolled 240 times and shows three on top 36 times, for a sample proportion of 0. Show supporting work. This outcome is independent from flight. Historically 22% of all adults in the state regularly smoked cigars or cigarettes.
At the inception of the clinic a survey of pet owners indicated that 78% of all pet dogs and cats in the community were spayed or neutered. Would you be surprised. Clearly the proportion of the population with the special characteristic is the proportion of the numerical population that are ones; in symbols, But of course the sum of all the zeros and ones is simply the number of ones, so the mean μ of the numerical population is. For large samples, the sample proportion is approximately normally distributed, with mean and standard deviation. D. An airline claims that there is a 0.10 probability. Sam will take 104 flights next year. An online retailer claims that 90% of all orders are shipped within 12 hours of being received.
Find the probability that in a random sample of 50 motorists, at least 5 will be uninsured. Which lies wholly within the interval, so it is safe to assume that is approximately normally distributed. A consumer group placed 121 orders of different sizes and at different times of day; 102 orders were shipped within 12 hours. He commissions a study in which 325 automobiles are randomly sampled.
In an effort to reduce the population of unwanted cats and dogs, a group of veterinarians set up a low-cost spay/neuter clinic. A humane society reports that 19% of all pet dogs were adopted from an animal shelter. This gives a numerical population consisting entirely of zeros and ones. Suppose that in a population of voters in a certain region 38% are in favor of particular bond issue. He knows that five years ago, 38% of all passenger vehicles in operation were at least ten years old. The proportion of a population with a characteristic of interest is p = 0. Suppose that one requirement is that at most 4% of all packages marked 500 grams can weigh less than 490 grams. The information given is that p = 0. Suppose random samples of size n are drawn from a population in which the proportion with a characteristic of interest is p. The mean and standard deviation of the sample proportion satisfy. A random sample of size 1, 100 is taken from a population in which the proportion with the characteristic of interest is p = 0. P is the probability of a success on a single trial. Item b: 20 flights, hence. Suppose that in 20% of all traffic accidents involving an injury, driver distraction in some form (for example, changing a radio station or texting) is a factor.
An economist wishes to investigate whether people are keeping cars longer now than in the past. An outside financial auditor has observed that about 4% of all documents he examines contain an error of some sort. In a survey commissioned by the public health department, 279 of 1, 500 randomly selected adults stated that they smoke regularly. For each flight, there are only two possible outcomes, either he receives an upgrade, or he dos not. Using the value of from part (a) and the computation in part (b), The proportion of a population with a characteristic of interest is p = 0. Suppose that 2% of all cell phone connections by a certain provider are dropped. Item a: He takes 4 flights, hence. 43; if in a sample of 200 people entering the store, 78 make a purchase, The sample proportion is a random variable: it varies from sample to sample in a way that cannot be predicted with certainty. To be within 5 percentage points of the true population proportion 0. First class on any flight. Assuming that a product actually meets this requirement, find the probability that in a random sample of 150 such packages the proportion weighing less than 490 grams is at least 3%. You may assume that the normal distribution applies.
In each case decide whether or not the sample size is large enough to assume that the sample proportion is normally distributed. 39% probability he will receive at least one upgrade during the next two weeks. N is the number of trials. Often sampling is done in order to estimate the proportion of a population that has a specific characteristic, such as the proportion of all items coming off an assembly line that are defective or the proportion of all people entering a retail store who make a purchase before leaving.
6 Distribution of Sample Proportions for p = 0. Be upgraded 3 times or fewer? A state insurance commission estimates that 13% of all motorists in its state are uninsured. Some countries allow individual packages of prepackaged goods to weigh less than what is stated on the package, subject to certain conditions, such as the average of all packages being the stated weight or greater. C. What is the probability that in a set of 20 flights, Sam will. Nine hundred randomly selected voters are asked if they favor the bond issue. Because it is appropriate to use the normal distribution to compute probabilities related to the sample proportion. 90,, and n = 121, hence. Be upgraded exactly 2 times? Suppose this proportion is valid. 1 a sample of size 15 is too small but a sample of size 100 is acceptable. Viewed as a random variable it will be written It has a mean The number about which proportions computed from samples of the same size center.
Of them, 132 are ten years old or older. If Sam receives 18 or more upgrades to first class during the next. Find the probability that in a random sample of 275 such accidents between 15% and 25% involve driver distraction in some form. First verify that the sample is sufficiently large to use the normal distribution. In a random sample of 30 recent arrivals, 19 were on time. 71% probability that in a set of 20 flights, Sam will be upgraded 3 times or fewer. Suppose that 8% of all males suffer some form of color blindness. Lies wholly within the interval This is illustrated in the examples.
Find the probability that in a random sample of 450 households, between 25 and 35 will have no home telephone. The probability of receiving an upgrade in a flight is independent of any other flight, hence, the binomial distribution is used to solve this question. An ordinary die is "fair" or "balanced" if each face has an equal chance of landing on top when the die is rolled. Thus the population proportion p is the same as the mean μ of the corresponding population of zeros and ones. Suppose that 29% of all residents of a community favor annexation by a nearby municipality. After the low-cost clinic had been in operation for three years, that figure had risen to 86%. To learn more about the binomial distribution, you can take a look at. Suppose 7% of all households have no home telephone but depend completely on cell phones. Find the probability that in a random sample of 600 homes, between 80% and 90% will have a functional smoke detector.
38, hence First we use the formulas to compute the mean and standard deviation of: Then so.
