- Using The t Distribution Table, find the critical value(s) for the / test for a two-tailed test with n=16 and a = 0.05. Enter the answers separated by a comma if needed. Critical value(s)= 0.0.probaUse the normal distribution of IQ scores, which has a mean of 100 and a standard deviation of 18, and the following table with the standard scores and percentiles for a normal distribution to find the indicated quantity. Percentage of scores less than 145 is __% (round to two decimal places as needed)
- The population of scores on a nationally standardized test forms a normal distribution with a mean of 300 and a standard deviation of 50. If you take a random sample of n = 25 students, what is the probability that the sample mean will be less than M = 280? Pls explain! Thx!A company produces steel rods. The lengths of the steel rods are normally distributed with a mean of 110.9 cm and a standard deviation of 2.1 cm. For shipment, 19 steel rods are bundled together.Find the probability that the average length of a randomly selected bundle of steel rods is less than 110.8 cm.P(M < 110.8 cm) = Enter your answer as a number accurate to 4 decimal places.A company produces steel rods. The lengths of the steel rods are normally distributed with a mean of 111.7-cm and a standard deviation of 1.4-cm. For shipment, 7 steel rods are bundled together.Find the probability that the average length of a randomly selected bundle of steel rods is between 111.5-cm and 112-cm.P(111.5-cm < M < 112-cm) = Enter your answer as a number accurate to 4 decimal places. Answers obtained using exact z-scores or z-scores rounded to 3 decimal places are accepted.
- Scores on a standardized exam are known to follow a normal distribution with a standard deviation of o = 8. A researcher randomly selects 84 students and finds their mean exam score to be I = 78. How confident are you that the mean score for all students taking the exam is in the interval (76.702, 79.298)? *Include 2 decimals places in your final answer* Confidence Level:Central Limit Theorem: When the maximum SAT score was 2400, scores had a mean = 1518 and standard deviation = 325. Assuming the scores are normally distributed, determine the probability of a score exceeding 1600. If 81 SAT scores are randomly selected, find the probability that their mean score exceeds 1600.Scores on a standardized exam are known to follow a normal distribution with standard deviation σσ = 17. A researcher randomly selects 85 students and computes their average score. He reports that the mean score is 76.3, with a margin of error of 2.792. How confident are you that the mean score for all students taking the exam is in the interval (73.508, 79.092)? Confidence =
