Find the probability that a randomly selected piece of data from a normal population will have a z-score between 1.28 and 2.25
A random sample of size n = 21, taken from a normal population with a standard deviation 04 =5, has a mean X4 = 90. A second random sample of size n2 = 37, taken from a different normal population with a standard deviation o2 = 4, has a mean X2 = 39.

find the probability that the sample mean of 16 observations from a standard normal distribution population, (normal distribution with u=0 and sigma=1), will be between -0.1 and 0.1
A sample of 46 observations is taken from a normal population with a standard deviation of 26. The sample mean is 44. Determine the 80% confidence interval for the population mean. (Round the final answers to 3 decimal places.) Confidence interval for the population mean is and
A population has a normal distribution with a mean of 50 and a standard deviation of 10. If a random sample of size 9 is taken from the population, then what is the probability that this sample mean will be between 48 and 54?
. In probability theory, the Normal Distribution (sometimes called a Gaussian Distribution or Bell Curve) is a very common continuous probability distribution. Normal distributions are important in statistics and are often used in the natural and social sciences to represent real-valued random variables whose distributions are not known. Describing the normal distribution using a mathematical function is called a probability distribution function (PDF) which is given here: H The mean of the distribution ơ-The standard deviation f(x)--e 2σ We can...
A random sample of 49 measurements from a population with population standard deviation o 3 had a sample mean of x, 9. An independeent random sample of sample mean of x, 11. Test the claim that the population means are 64 measurements from a second population with population standard deviation a2 4 had different. Use level of significance 0.01. (a) What distribution does the sample test statistic follow? Explain. The student's t. We assume that both population distributions are approximately...
What would be the minimum sample size, taken from a normal population with standard deviation 1, to ensure we are 95% confident our estimate within .01 of the true population mean?
