1. Mark 30 small pieces of paper with an A, a B, or a C. Put the pieces of paper in a bag. Trade bags with other students in the class. a. Generate a sample by choosing a piece of paper from your bag 10 times, replacing the piece of paper each time. Record the number of times you choose each letter. Repeat this process to generate five more samples. b. Use each sample to make an estimate for the number of As and Bs in the bag. Then describe the variation of the six estimates. Make estimates for the numbers of As, Bs, and Cs in the bag based on all the samples. c. Take the pieces of paper out of the bag. How do your estimates compare to the population? Do you think you can make a more accurate estimate? If so, explain how.
A population consists of the numbers 2,3,4,5, and 6. Let us list all possible sample size of 3 from this population and compute the mean of each sample.Using the formula Ncn wher N is the population size and n is the sample size.
Three randomly selected children are surveyed. The ages of the children are 3, 5, and 10. Assume that samples of size n= 2 are randomly selected with replacement from the population of 3, 5, and 10. Listed below are the nine different samples. Complete parts (a) through (d). 3,3 3,5 3,10 5,3 5,5 5,10 10,3 10,5 10,10 . a. For the population, find the proportion of odd numbers. The proportion is (Round to three decimal places as needed) b. Find the proportion of odd numbers of each of the nine samples, then summarize the sampling distribution of the medians in the format of a table representing the probability distribution of the distinct proportion values ce!

The mean is (Round to three decimal places as needed ) Next Activane
You are the operations manager for an airline and you are considering a higher fare level for passengers in aisle seats. How many randomly selected air passengers must you survey? Assume you want to be 90% confident that the sample percentage is within 2.5 percentage points of the true population percentage. Completed parts a and b below. A.) assume that nothing is known about the percentage of passengers who prefer aisle seats. N= ____ (round up to the nearest integer) B.) assume that a prior survey suggest that about 35% of air passengers prefer an aisle seat. N=____ (round up to the nearest integer)
Three randomly selected households are surveyed. The numbers of people in the households are 4, 5, and 9. Assume that samples of size n= 2 are randomly selected with replacement from the population of 4, 5, and 9. Listed below are the nine diff Print samples. Complete parts (a) through (c). 4,4 4,5 4,9 5,4 5,5 5,9 9,4 9,5 9,9 D a. Find the median of each of the nine samples, then summarize the sampling distribution of the medians in the format of a table representing the probability distribution of the distinct median values. Sample Median (1) Probability (2) (3) (4) (5) (6) (Type integers or fractions. Use ascending order of the sample medians.) b. Compare the population median to the mean of the sample medians. Choose the correct answer below. O A. The population median is equal to half of the mean of the sample medians. O B. The population median is not equal to the mean of the sample medians (it is also not half or double the mean of the sample medians).
