The police tested 550 people, to see if anyone would match the partial fingerprint at the crime scene. The probability of getting a false-positive result for a single person, was 0.3%. In the video: What did we find was the approximate percentage probability, that out of 550 people tested, there would be at least one false-positive result? Round to four digits past the decimal point, and include a percentage symbol in your answer (with no spaces).
The chances of a pine tree in a particular forest being effected by the pine beetle is 10 percent. If you randomly select 20 trees for testing, what is the probability that fewer than 2 will be infected by the pine beetle? Round your answer to three decimal places, e.g. 0.619.
In the winter, guests who visit Yosemite National Park like to stay at an overnight lodge in the park 71 % of the time. Find the probability that among 11 guests surveyed exactly 3 guests like to stay at an overnight lodge in the park. P(x = 3) =
A sample of 400 adults found that 82 have high blood pressure. However, 98 of those studied reported being unwilling to change their diet. Based on this sample, if an adult is chosen at random, what is the probability that he or she is open to trying to eat more healthfully? Express your answer as a fraction in lowest terms or a decimal rounded to the nearest millionth.
A real estate agent has 18 properties that she shows. She feels that there is a 50% chance of selling any one property during a week. The chance of selling any one property is independent of selling another property. Compute the probability of selling less than 5 properties in one week. Round your answer to four decimal places.
The CEO of a large electric utility claims that at least 80 percent of his one million customers are very satisfied with the service they receive. A local newspaper surveyed 300 customers randomly. 73 percent said they were very satisfied. The test statistic is (Round answer to two decimal places. Do not write 0.12 as .12.)
Mrs. Berry claims to produce random numbers from 1 to 5 (inclusive) on her calculator, but you've been keeping track. In the past 80 selections, the number "five" has come up only 8 times. You suspect that the calculator is producing fewer fives than it should. Let p = the true long-run proportion of five's produced by the calculator. What is the approximate P-value for this test? 0.0028 O -2.24 O 0.0250 O -2.98 O 0.0126

Yes No Yes 62 84 No 281 551 If two different pedestrian deaths are randomly selected, find the probability that they both involved drivers that were intoxicated.Report the answer rounded to four decimal place accuracy.
A soccer team estimates that they wil score on 12% of the comer kicks. In next week's game, the team hopes to kick 13 coner kicks. What are the chances that they will score on 4 of those opportunities? The probability is (Type an integer or a decimal. Round to three decimal places as needed.)
Find the indicated probability and interpret the result. From 1975 through 2020, the mean annual gain of the Dow Jones Industrial Average was 651. A random sample of 32 years is selected from this population. What is the probability that the mean gain for the sample was between 400 and 700? Assume o = 1540. The probability is (Round to four decimal places as needed.)
