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 0.426 for a negative test result? Did the Subject Actually Lie? No (Did Not Lie) Yes (Lied) Positive test results 12 46 Negative test results 29 14 The probability that a randomly selected polygraph test subject was not lying is nothing. (Type an integer or decimal rounded to three decimal places as needed.)
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 0.476 for a negative test result? Did the Subject Actually Lie? 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.
Students investigating the packaging of tortilla chips purchased 6 bags of chips marked with a net weight of 29.4 grams. They carefully weighed the contents of each bag, recording the following weights (in grams): 29.1, 28.1, 29.4, 28.6, 28.7, 28.8. Complete parts a through f below. a) Do these data satisfy the assumptions for inference? Explain. O A. The Randomization Condition is not met and cannot be assumed to be true. The histogram is unimodal and roughly symmetric, so the Nearly Normal Condition is met. O B. The Randomization Condition is met. The histogram is bimodal and not symmetric, so the Nearly Normal Condition is not met. O.C. The Randomization Condition is met. The histogram is extremely skewed right, so the Nearly Normal Condition is not met. D. The Randomization Condition may not be satisfied. However, it is reasonable to think that these bags are representative of all bags of chips. The histogram is unimodal and roughly symmetric, so the Nearly Normal Condition is met.…
Question Help v A candy company says that the colors of its candies are 15% yellow, 14% red, 21% orange, 23% blue, 16% green and 11% brown. In a randomly selected bag of the candies, there were 28 yellow, 21 red, 10 orange, 10 blue, 5 green, 19 brown. Is this sample consistent with the company's advertised proportions? Test an appropriate hypothesis and state your conclusion. Complete parts a through g below. a) If the company's candies are packaged in the advertised proportions, how many of each color should have been expected in the bag of candies Red (Type integers or decimals rounded to two decimal places as needed.)
