Item a: He takes 4 flights, hence. Find the indicated probabilities. Samples of size n produced sample proportions as shown. Suppose that one requirement is that at most 4% of all packages marked 500 grams can weigh less than 490 grams. 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. If Sam receives 18 or more upgrades to first class during the next. In the same way the sample proportion is the same as the sample mean Thus the Central Limit Theorem applies to However, the condition that the sample be large is a little more complicated than just being of size at least 30. An airline claims that there is a 0.10 probability and statistics. The proportion of a population with a characteristic of interest is p = 0. Which lies wholly within the interval, so it is safe to assume that is approximately normally distributed. An airline claims that there is a 0.

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%. An airline claims that there is a 0.10 probability of competing beyond. The information given is that p = 0. Suppose that 8% of all males suffer some form of color blindness. 38, hence First we use the formulas to compute the mean and standard deviation of: Then so. He commissions a study in which 325 automobiles are randomly sampled.

A state insurance commission estimates that 13% of all motorists in its state are uninsured. 71% probability that in a set of 20 flights, Sam will be upgraded 3 times or fewer. Suppose this proportion is valid. Nine hundred randomly selected voters are asked if they favor the bond issue. To be within 5 percentage points of the true population proportion 0. 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. Be upgraded exactly 2 times? N is the number of trials. Thus the population proportion p is the same as the mean μ of the corresponding population of zeros and ones. 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. An airline claims that there is a 0.10 probability density. 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. Using the binomial distribution, it is found that there is a: a) 0. You may assume that the normal distribution applies.

An Airline Claims That There Is A 0.10 Probability Of Competing Beyond

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. An economist wishes to investigate whether people are keeping cars longer now than in the past. Suppose 7% of all households have no home telephone but depend completely on cell phones. The sample proportion is the number x of orders that are shipped within 12 hours divided by the number n of orders in the sample: Since p = 0.

In actual practice p is not known, hence neither is In that case in order to check that the sample is sufficiently large we substitute the known quantity for p. This means checking that the interval. A random sample of size 1, 100 is taken from a population in which the proportion with the characteristic of interest is p = 0. The Central Limit Theorem has an analogue for the population proportion To see how, imagine that every element of the population that has the characteristic of interest is labeled with a 1, and that every element that does not is labeled with a 0. Find the probability that in a random sample of 600 homes, between 80% and 90% will have a functional smoke detector.

An online retailer claims that 90% of all orders are shipped within 12 hours of being received. 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. An outside financial auditor has observed that about 4% of all documents he examines contain an error of some sort. Be upgraded 3 times or fewer? Lies wholly within the interval This is illustrated in the examples. 38 means to be between and Thus. Item b: 20 flights, hence. Find the mean and standard deviation of the sample proportion obtained from random samples of size 125.

He knows that five years ago, 38% of all passenger vehicles in operation were at least ten years old. In a random sample of 30 recent arrivals, 19 were on time. Here are formulas for their values. This outcome is independent from flight. A state public health department wishes to investigate the effectiveness of a campaign against smoking. For large samples, the sample proportion is approximately normally distributed, with mean and standard deviation. First class on any flight. The parameters are: - x is the number of successes. 39% probability he will receive at least one upgrade during the next two weeks.

5 a sample of size 15 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. B. Sam will make 4 flights in the next two weeks. Binomial probability distribution. Suppose that 29% of all residents of a community favor annexation by a nearby municipality. Show supporting work. Because it is appropriate to use the normal distribution to compute probabilities related to the sample proportion.

For each flight, there are only two possible outcomes, either he receives an upgrade, or he dos not. Suppose that 2% of all cell phone connections by a certain provider are dropped.

In an effort to reduce the population of unwanted cats and dogs, a group of veterinarians set up a low-cost spay/neuter clinic. Of them, 132 are ten years old or older.

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. Historically 22% of all adults in the state regularly smoked cigars or cigarettes. First verify that the sample is sufficiently large to use the normal distribution. 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. Suppose that in a population of voters in a certain region 38% are in favor of particular bond issue. Assuming this proportion to be accurate, find the probability that a random sample of 700 documents will contain at least 30 with some sort of error. The population proportion is denoted p and the sample proportion is denoted Thus if in reality 43% of people entering a store make a purchase before leaving, p = 0. A sample is large if the interval lies wholly within the interval. To learn more about the binomial distribution, you can take a look at. Sam is a frequent flier who always purchases coach-class.

The probability is: In which: Then: 0. In one study it was found that 86% of all homes have a functional smoke detector. 6 Distribution of Sample Proportions for p = 0. Would you be surprised. Assuming the truth of this assertion, find the probability that in a random sample of 80 pet dogs, between 15% and 20% were adopted from a shelter. 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.

P is the probability of a success on a single trial. And a standard deviation A measure of the variability of proportions computed from samples of the same size.
