Let's examine the mean of the numbers 1, 2, 3, 4, 5, 6, 7, and 8 by drawing samples from these values, calculating the mean of each sample, and then considering the sampling distribution of the mean. To do this, suppose you perform an experiment in which you roll an eight-sided die two times (or equivalently, roll two eight-sided dice one time) and calculate the mean of your sample. Remember that your population is the numbers 1, 2, 3, 4, 5, 6, 7, and 8. The true mean (µ) of the numbers 1, 2, 3, 4, 5, 6, 7, and 8 is , and the true standard deviation (o) is The number of possible different samples (each of size n = 2) is the number of possibilities on the first roll (8) times the number of possibilities on the second roll (also 8), or 8(8) = 64. If you collected all of these possible samples, the mean of your sampling distribution of means (µM) would equal and the standard deviation of your sampling distribution of means (that is, the standard error or ɑm) would be The following chart…

In a university of 1,000 students a survey was to be taken to determine how many students are left-handed. It was found out that 8% of the student population are left-handed. 2. A study in the wake of a natural disaster divides a population according to region, then choose a region randomly to begin establishing the disaster's overall effect. 3. A pharmaceutical company wants to test the effectiveness of a new drug. The first group will receive the new drug; the second group will receive a placebo. 4. A study was conducted to determine whether a new schooling program affects the test scores of students. The scores were grouped by family income category. 5.
