The sample proportion is approximately normally distributed.
Here .
Thus,
Therefore,
We need to find 75-th percentile of the distribution (say )
Use the Central Limit Theorem to find a proportion given a probability - Excel Question A...
Using excel!!!!!!!!! H. Use the Central Limit Theorem to find the probability below: 22. Your lumber company has bought a machine that automatically cuts lumber. The seller of the machine claims that the machine cuts lumber to a mean length of 8 ft. (96 in.) with a standard deviation of 0.5 inch. Assume the lengths are normally distributed. You randomly select 40 boards and find that the mean length is 96.25 inches. a) What is the probability that mean of...
Use the Central Limit Theorem for Sums to find the sample mean and sample standard deviation Question Suppose weights, in pounds, of dogs in a city have an unknown distribution with mean 26 and standard deviation 3 pounds. A sample of size n = 67 is randomly taken from the population and the sum of the values is computed. Using the Central Limit Theorem for Sums, what is the mean for the sample sum distribution? Provide your answer below: pounds
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 105 pounds and a standard deviation of 37.3 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 devoted, with a mean of 116 pounds and a standard deviation of 37.0 pounds. Random samples of size 19 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 120 pounds and a standard deviation of 39.7 pounds. Random samples of size 18 are drawn from this population and the mean of each sample is determined. 0
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 (optional) 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 39.5 pounds. Random samples of size 19 are drawn from this population and the mean of each sample is determined
Question 3 (4 points) In a population μΥ-100 and 43. Use the central limit theorem to answer the following questions (a) In a random sample of size n-100, find PY 101] (b) In 64, find P[101 Y < 103 a random Sample of size n
Understand sampling distributions and the Central Limit Theorem for Proportions Question From recent census data, it is discovered that the proportion of the adults in the United States who are first generation Americans is 14%. For a random sample of size 500, what is standard deviation for the sampling distribution of the sample proportions, rounded to three decimal places? Provide your answer below:
Use the Central Limit Theorem to find the mean and standard error of the mean of the sampling distribution. Then sketch a graph of the sampling distribution. The mean price of photo printers on a website is $243 with a standard deviation of $59. Random samples of size 26 are drawn from this population and the mean of each sample is determined. The mean of the distribution of sample means is _______.
Use the Central Limit Theorem to find the mean and standard error of the mean of the sampling distribution. Then sketch a graph of the sampling distribution. The mean price of photo printers on a website is $240 with a standard deviation of $60. Random samples of size 35 are drawn from this population and the mean of each sample is determined.
