Determine the finite population correction factor for each of the following. (a) N-2000 and n 1500...
When a population is finite, the formula that determines the standard error of the mean o- needs to be adjusted. If N is the size of the population and n is the size of the N -n N -n sample (where n 20.05N), then the standard error of the mean is 0-=- .. The expression H i s called the finite population correction factor. Use the V N -1 finite population correction factor to construct the confidence interval for the...
Determine if the finite correction factor should be used. If so, use it in your calculations when you find the probability. In a sample of 700 gas stations, the mean price for regular gasoline at the pump was $ 2.854 per gallon and the standard deviation was $0.009 per gallon. A random sample of size 45 is drawn from this population. What is the probability that the mean price per gallon is less than $2.851? The probability that the mean...
Determine if the finite correction factor should be used. If so, use it in your calculations when you find the probability. In a sample of 800 gas stations, the mean price for regular gasoline at the pump was $ 2.849 per gallon and the standard deviation was $0.008 per gallon. A random sample of size 50 is drawn from this population. What is the probability that the mean price per gallon is less than $2.847? The probability that the mean...
A random sample of size n = 87 is taken from a population of size N = 847 with a population proportion p = 0.75. [You may find it useful to reference the z table.] a-1. Is it necessary to apply the finite population correction factor? a-2. Calculate the expected value and the standard error of the sample proportion. (Round "expected value" to 2 decimal places and "standard error" to 4 decimal places.) b. What is the probability that the...

A random sample of size n = 124 is taken from a population of size N = 3,835 with a population proportion of p = 0.63. [You may find it useful to reference the z table.] a-1. Is it necessary to apply the finite population correction factor? Yes No a-2. Calculate the expected value and the standard error of the sample proportion. (Round "expected value" to 2 decimal places and "standard error" to 4 decimal places.) b. What is the...
A random sample of size n=68 is taken from a finite population of size N=644 with mean y = 239 and variance o?. 325. [You may find it useful to reference the table.) 8-1. Is it necessary to apply the finite population correction factor? Yes No 0-2. Calculate the expected value and the standard error of the sample mean (Round "expected value to a whole number and standard error to 4 decimal places.) Answer is complete but not entirely correct....
Suppose a random sample of size 40 is selected from a population with σ = 8. Find the value of the standard error of the mean in each of the following cases. (Use the finite population correction factor if appropriate. Round your answers to two decimal places.) (a) The population size is infinite. (b) The population size is N = 40,000. (c) The population size is N = 4,000. (d) The population size is N = 400.
A random sample of size n = 347 is taken from a population of size N = 7,200 with mean μ =-70 and variance ơ2-151. Use Table 1. a-1. Is it necessary to apply the finite population correction factor? Yes O No a-2. Calculate the expected value and the standard error of the sample mean. (Negative values should be indicated by a minus sign. Round "standard error" to 2 decimal places.)
