In a recent study on world happiness, participants were asked to evaluate their current lives on a scale from 0 to 10, where 0 represents the worst possible life and 10 represents the best possible life. The responses were normally distributed, with a mean of 4.9 and a standard deviation of 2.3. (a) Find the probability that a randomly selected study participant's response was less than 4.
Scores for men on the verbal portion of the SAT-I test are normally distributed with a mean of 509 an a standard deviation of 112. (a) If 1 man is randomly selected, find the probability that his score is at least 582.5. (b) If 17 men are randomly selected, find the probability that their mean score is at least 582.5. 17 randomly selected men were given a review course before taking the SAT test. If their mean score is 582.5, is there a strong evidence to support the claim that the course is actually effective? (Enter YES or NO)
A sample of size n=5 is selected from a population. Under what conditions is the sampling distribution of normal? In this problem, suppose the population mean is 125 and the population standard deviation is 20. What are the expected value and the standard error of sample mean?
The death age for men in 2010 follows an unknown left-skewed distribution with a mean of 76.3 years and a standard deviation of 10.2 years. We look at a sample of 67 men who died in the US in 2010. What is the distribution of the average age at death (in years) computed from 67 randomly sampled male deaths? [ Select ] What is the probability that the mean age at death in years of this random sample of 67 deaths is greater than 80? [ Select ] Instead of 67 deaths, I took a sample smaller than 67 deaths and computed the mean. Is the probability of this mean being more than 80 years greater than, less than, or equal to the probability calculated in the previous question? [ Select] What is the 86th percentile of the sampling distribution for the mean age at death from the random sample of 67? [ Select ] Is the 86th percentile of the sampling distribution for the mean age at death from a sample larger than 67 greater than, less than, or equal to the result in the previous question? [ Select…
When engaging in weight-control (fitness/fat burning) types of exercise, a person is expected to attain approximately 60% of his or her maximum heart rate. For 20-year-olds, this rate is approximately 120 bpm. A simple random sample of thirty 20-year-olds was taken, and the sample mean was found to be 107 bpm, with a standard deviation of 45 bpm. Researchers wonder if this is evidence to conclude that the expected level is actually lower than 120 bpm. Report a 95% confidence region for the mean level of heart rate for this group. the mean level of heart rate is lower than 120.96 the mean level of heart rate is greater than 114.47 the mean level of heart rate is greater than 117.67 the mean level of heart rate is lower than 114.47
The SAT mathematics scores across the population of high school seniors are a normal random variable with a mean of 500 and a standard deviation of 100. Assume that the SAT mathematics test scores of different students are independent. (a) Find the probability that five randomly chosen seniors all score below 600. (b) What score must a student obtain to be in the 99th percentile?
Show neat and complete solution. (... The average fuel efficiency of U.S. light vehicles (cars, SUVs, minivans, vans, and light trucks) for 2005 was 21 miles per gallon (mpg). If the standard deviation of the population was 2.8 and the gas ratings were normally distributed, (a) what is the probability that the mean mpg for a random sample of 25 light vehicles is under 18? (b) between 20 and 24? Given: Required: Solution: a. b.
A researcher selected a sample of 156 former student leaders from a list of graduates of a large university. She discovered that it had taken an average of 4.97 years for the graduates to finish their degrees, with a standard deviation of 1.23. The average for the entire student body is 4.56 years. Is the difference statistically significant? Alpha = 0.05; two-tailed test.
