When a population is finite, the formula that determines the standard error of the mean needs to be adjusted. If N is the size of the population and n is the size of the sample (where n ≥ 0.05N), the standard error of the mean is shown below. The finite population correction factor is given by the expression √(N-n)/(N-1). Determine the finite population correction factor for each of the following. (a) N = 1400 and n = 1050 (b) N = 1400 and n = 140 (d) N = 1400 and n = 70 (c) N = 1400 and n = 75 (e) What happens to the finite population correction factor as the sample size n decreases but the population size N remains the same? (a) The finite population correction factor is (Round to three decimal places as needed.) (b) The finite population correction factor is (Round to three decimal places as needed.) (c) The finite population correction factor is (Round to three decimal places as needed.) (d) The finite population correction factor is (Round to three decimal places as needed.) (e)…

Let X₁, X₂, ‚X₂be i.i.d. with following probability mass function 0.1 +0, x = 1 x = 2 x = 3 S p(x 10) = 0.5, 0.4-0, where -0.1 ≤ 0 ≤ 0.4 1. Find a reasonable estimator of 0. 2. Suppose that n = 1, find a most powerful text (with level 0.1) for Ho: 0 = 0 versus HA: 0 = 0.3 3. Suppose that n = 1, and the test hypothesis is H : 0 = 0 versus H₁ : 0 > 0, does a uniformly most powerful test exist? If it exists, please find it.

The following table was generated from the sample data of 1010 college students regarding the number of parking tickets the student receives in a semester, the student's age, and the student's GPA. The dependent variable is the student's GPA, the first independent variable (x1�1) is the number of parking tickets, and the second independent variable (x2�2) is the student's age.
