- The distribution of the arrival times of students coming to Chemistry class late is not normally distributed. A sample of 33 students is taken, with mean, μ=3.2 and standard deviation, σ=8.4. Is Central Limit Theorem applicable in the following cases? Explain why.The National Vaccine Information Center estimates that 90% of Americans have had chickenpox by the time they reach adulthood. Suppose we take a random sample of 100 American adults. Use the Central Limit Theorem to compute the standard error for the sampling distribution. Write you answer as a decimal rounded to three places.Use the central limit theorem to find the mean and standard error of the mean of the indicated sampling distribution. Then sketch a graph of the sampling distribution. The per capita consumption of red meat by people in a country in a recent year was normally distributed, with a mean of 113 pounds and a standard deviation of 37.7 pounds. Random samples of size 20 are drawn from this population and the mean of each sample is determined.
- Use the central limit theorem to find the mean and standard error of the mean of the indicated sampling distribution. Then sketch a graph of the sampling distribution. The per capita consumption of red meat by people in a country in a recent year was normally distributed, with a mean of 106 pounds and a standard deviation of 38.6 pounds. Random samples of size 17 are drawn from this population and the mean of each sample is determined. Ux = Standard deviation =Let X be the time between successive arrivals to an intersection in a rural area. Suppose cars arrive to the intersection via a Poisson process at a rate of 1 every 5 minutes. (a) What distribution does X have? (b) What is the mean time between arrivals? (c) What is the probability that more than 7 minutes will pass between arrivals to the inter-section?The total cholesterol levels for women aged 20 to 30 years are normally distributed with µ=190 mg/dl and σ=40 mg/dl. A sample of 25 women in this age-group is randomly selected. What range of cholesterol series is expected for the middle 99% of all sample means?
- Use the central limit theorem to find the mean and standard error of the mean of the indicated sampling distribution. Then sketch a graph of the sampling distribution. The per capita consumption of red meat by people in a country in a recent year was normally distributed, with a mean of 116 pounds and a standard deviation of 38.3. pounds. Random samples of size 20 are drawn from this population and the mean of each sample is determined. μx=____Inclusions are defects in poured metal caused by contaminants. The number of (large) inclusions in cast iron follows a Poisson distribution with a rate of 3.4 per cubic millimetre. What is the probability of at least one inclusion in a cubic millimetre? Please enter the answer to 3 decimal places.Inclusions are defects in poured metal caused by contaminants. The number of (large) inclusions in cast iron follows a Poisson distribution with a rate of 1.9 per cubic millimetre. What is the volume of material to inspect such that the probability of at least one inclusion is 0.99? Please enter the answer to 2 decimal places.
- Define the homoskedasticity-only F-statistic when n is small?What is the Central Limit Theorem? It is always true that as the sample size, n, increases, the distribution of the sample means will be approximately normally distributed. ExplainA researcher in an alcoholism treatment center, interested in summarizing the length of stay in the center for first-time patients, randomly selects nine records of individuals institutionalized within the previous two years. The lengths of stay in the center, in days, are as follows 11, 7, 20, 9, 13, 4, 13, 14, and 8. a.What are the measures of central tendency for this distribution? (Show calculations) b.Show two measures of variation for this distribution? (Show calculations)
