Determine the minimum sample size required when you want to be 99% confident that the sample mean is within one unit of the population mean and σ=12.3. Assume the population is normally distributed.
Suppose that X is a normal random variable with mean 48.5 and standard deviation = 6.8. Let denote the variable for the process of taking a random sample and calculating the sample mean (We called this the sampling distribution of the sample mean). Suppose that the sample size is 22. Calculate the Z-score associated with observing a sample mean of 51.4. Enter your answer to two decimal places. Hint: Use the formula to compute the Z-score x - HX

If μx = 30 and σx = 4, Determine P(X<31) for n = 4. a) What is the mean,μx, of the random variable? b) What is the standard deviation,σx, of the random variable? **I am mainly confused whether the S.D. for part (b) would be the value that is given (σx = 4) or if it is "σ/√n" (which would be 4/√4 = 2).

A random sample of size n1 =15 is selected from a normal population with a mean of 76 and standard deviation of 9. A second random sample size n2 =10 is taken from another normal population with mean 71 and a standard deviation 13. Let x barı and x bar2 be the sample means. Find: a.

It is believed that the mean value of a variable measured for an entire population of individuals has value µ = 17 and that for the population the standard deviation is σ = 5.69. A sample of size n= 43 is to be taken from the population. According to the central limit theorem, the sampling distribution of the mean is Normal( 43 , 0.872 ) Normal( 17 , 5.692 ) Normal( 17 , 0.872 ) Normal( 43 , 5.692 )

A large airline company called Fusion Fly monitors customer satisfaction by asking customers to rate their experience as a 1, 2, 3, 4, or 5, where a rating of 1 means "very poor" and 5 means "very good". The customers' ratings have a population mean of μ = 4.29, with a population standard deviation of a = 1.15. Suppose that we will take a random sample of n=7 customers' ratings. Let x represent the sample mean of the 7 customers' ratings. Consider the sampling distribution of the sample mean x. Complete the following. Do not round any intermediate computations. Write your answers with two decimal places, rounding if needed. (a) Find μ- (the mean of the sampling distribution of the sample mean). H₂=0 X (b) Find o- (the standard deviation of the sampling distribution of the sample mean). 0--0 X
