Each student in a statistics class was asked to randomly select a number from 1 to 10. The graph below summarizes their choices. The height of the bar above a number indicates the percentage of students in the class that chose that number (the actual percentage is shown above the bar). A) what is the median of all the numbers selected by the students? B) what is the first quartile Q1 of all the numbers selected by the students? What is the third quartile Q3 of all the numbers selected by the students?
6. What is the probability of rolling a number greater than four on a standard 6- sided die?
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…
