  1. Suppose you had six homework assignments during the semester and received the following scores: 79, 64, 84, 82, 92, and 77. Your professor decided to randomly select two scores, compute the mean, and use this score to determine your final grade

    1. What is the population mean?

    2. How many different samples of two test grades are possible? List all of them and compute the mean of each.

    3. Compute the mean of the sample means and compare it to the population mean.

    4. Is this an arrangement you should accept? Would the result be different from dropping the lowest score?

Suppose your statistics instructor gave six examinations during the semester. You received the following exam scores (percent correct): 92, 70, 84, 87, 90, and 75. To compute your final course grade, the instructor decided to randomly select two exam scores, compute their mean, and use this score to determine your final course grade. Compute the population mean. This is your average grade based on all of your grades. (Round your answer to 2 decimal places.) Compute the population standard deviation....

Suppose your statistics instructor gave six examinations during the semester. You received the following exam scores (percent correct): 95, 64, 82, 88, 92, and 73. To compute your final course grade, the instructor decided to randomly select two exam scores, compute their mean, and use this score to determine your final course grade. Compute the population mean. This is your average grade based on all of your grades. (Round your answer to 2 decimal places.) Compute the population standard deviation....

The scores on the final of a math class last semester had a median of 28 out of 40, with the highest score of 39 and a lowest score of 6. Suppose that the curve had a normal distribution. Suppose I took a simple random sample of 3 students from last semester and found their scores on the final to be 15, 30, and 36. We wish to test the hypothesis that the average of all the students in the...

Of the ten students who received an "A+" in a class during the fall 2019 semester, three were sophomores, two were juniors, and one was a senior (the remaining student(s) were in their first year). the teacher believes four of the ten students are strong candidates for TA positions. Determine the probability the four candidates include exactly one student from each year in college.

find the following critical t-scores Near the beginning of the semester, you administered a survey to 10 students. Suppose we wanted to use your sample to calculate the mean age of college students. What are the critical t-scores for the mean age using your sample? 80% CI: t = 90% CI: t = 99% CI: t =

A college administrator would like to determine how much time students spend on homework assignments during a typical week. It is known that the standard deviation for the time students spend on homework is 3 hours per week.    A questionnaire is sent to sample of n=100 students and their response indicates a mean of 7.4 hours per week. Now make an interval estimate of population mean so that you are 99% confident that the "true" mean is in your interval....
