- You are planning a sample survey of small businesses in your area. You will choose an SRS of 150 businesses listed in the Yellow Pages. Experience shows that only half of the businesses you contact will respond. We consider each response as a success. a) What is the mean number who respond to this survey? b) What is the probability that 70 or fewer will respond? c) How large a sample must you take to increase the mean number of respondents to 100?Organ Donors USA Today provided information about a survey of 5100 adult Internet users. Of the respondents, 2346 said they are willing to donate organs after death. In this survey conducted for Donate Life America, 100 adults were surveyed in each state and the District of Columbia, and results were weighted to account for the different state population sizes. a. What percentage of respondents said that they are willing to donate organs after death? b. Based on the poll results, what is the probability of randomly selecting an adult who is willing to donate organs after death? c. What term is used to describe the sampling method of randomly selecting 100 adults from each state and the District of Columbia?Three items are drawn in randomly from a population of 7 items. The item drawn may be defective or non-defective. Random variable is the occurrence of non-defective items. Total defective items in the population are two.a. Make a frequency distribution table of the random variable. b. Find the expected value of non-defective items in the random experiment.
- Refer to the sample data for polygraph tests shown below. If one of the test subjects is randomly selected, what is the probability that the subject is not lying?

No (Did Not Lie) Yes (Lied) Positive test results 16 39 Negative test results 36 14 The probability that a randomly selected polygraph test subject was not lying is (Type an integer or decimal rounded to three decimal places as needed.) Is the result close to the probability, rounded to three decimal places, of 0.476 for a negative test result? because there is a 0.050 absolute difference between the probability of a true response and the probability of a negative test result.Refer to the sample data for polygraph tests shown below.

No (Did Not Lie) Yes (Lied) Positive test results 10 46 Negative test results 37 11 The probability that a randomly selected polygraph test subject was not lying is: (Type an integer or decimal rounded to three decimal places as needed.) Is the result close to the probability, rounded to three decimal places, of 0.462 for a negative test result? because there is Va 0.050 absolute difference between the probability of a true response and the probability of a negative test result.Refer to the sample data for polygraph tests shown below. If one of the test subjects is randomly selected, what is the probability that the subject is not lying? Is the result close to the probability of 0.443 for a negative test result? Did the Subject Actually Lie? No (Did Not Lie) Yes (Lied) O Positive test results 10 44 Negative test results 36 The probability that a randomly selected polygraph test subject was not lying is (Type an integer or decimal rounded to three decimal places as needed.) Is the result close to the probability, rounded to three decimal places, of 0.443 for a negative test result? because there is V a 0.050 absolute difference between the probability of a true response and the probability of a negative test result. Enter your answer in the answer box. Prise 6. LEGOd. Assuming a sample size of 76, what is the probability that the sampling error is within $1000. (In other words, the sample mean is within $1000 of the true mean.)
