niversity 37% of the students support the green party. Suppose a sample of size 94 students and are interested in the population proportion of students who support that party. Find the sampling distribution of sample proportion.

A coach is interested in how many slam dunks the average college freshman at his university can do. Ten volunteers from the senior class step forward. After observing their performance, the coach concluded that college seniors can do an average of 10 slam dunks in a row without missing. what is the sample? what is the population?

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…

There are eight patients waiting in a doctor's waiting room.  They have been waiting for 9 minutes, 2 minutes, 5 minutes, 4 minutes, 12 minutes, 7 minutes, 8 minutes, and 11 minutes.  Calculate the sample variance for the patients' wait times (in minutes squared). Round to the nearest hundredth as needed.

You randomly selected one sample of 40 citizens of your city to see if they wanted to increase taxes for education but you decided that you would do half younger people and half older people. Explain your answers. Is this random sampling?   Is this simple random sampling?

Of a graduate school that has 2000 business majors, 500 finance majors and 300 biology majors, a researcher starts at the least-numbered student ID and continues until she has collected the names of 200 business students, 50 finance students and 30 biology students. What type of sampling technique does this represent? Explain your reasoning.

A hockey coach wants to show that there is no relationship between player attitudes about their most recent loss and the career choice of their father. What sampling method is the hockey coach using?

determine which sampling method was used (simple random, cluster, convenience, stratified, systematic), and brieflystate how you were able to identify the type of sampling being used   A student surveys 30 people who happen to be on campus at 1:00 pm on a Monday.

A coach puts the names of all the basketball players into a hat and draws one name for a free basketball. Which sampling method is being used?
