The assets (in billions of dollars) of the four wealthiest people in a particular country are 40, 33, 19, 17. Assume that samples of size n=2 are randomly selected with replacement from this population of four values. a. After identifying the 16 different possible samples and finding the mean of each sample, construct a table representing the sampling distribution of the sample mean. In the table, values of the sample mean that are the same have been combined Probability x Probability 26 25 19 18 17 ✓ 40 36.5 33 29.5 28.5 (Type integers or fractions.) b. Compare the mean of the population to the mean of the sampling distribution of the sample mean. the mean of the sample means, The mean of the population, is (Round to two decimal places as needed.) c. Do the sample means target the value of the population mean? In general, do sample means make good estimates of population means? Why or why not? The sample means make good estimates of population means because the mean is the population mean. In general, sample means estimator. an unbiased a biased

Five pulse rates are randomly selected from a set of measurements. The five pulse rates have a mean of 76.6 beats per minute. Four of the pulse rates are 82, 59, 84, and 89. a. Find the missing value. b. Suppose that you need to create a list of n values that have a specific known mean, Some of the n values can be freely selected. How many of the n values can be freely assigned before the remaining values are determined? (The result is referred to as the number of degrees of freedom.)

Cal Poly Pomona found that 15% of its students withdraw without completing Calculus I course. Assume that 30 students registered for the course. Let X be the number of students who withdraw. What distribution does X follow?

Five pulse rates are randomly selected from a set of measurements. The five pulse rates have a mean of 70.4 beats per minute. Four of the pulse rates are 83, 75, 91, and 51. a. Find the missing value. b. Suppose that you need to create a list of n values that have a specific known mean. Some of the n values can be freely selected. How many of then values can be freely as beats per minute. a. The missing value is (Type an integer or a decimal. Do not round.) b. Select the correct choice below and fill in the answer box to complete your choice. (Type an expression using n as the variable.) O A. Of the n values, can be freely selected because the remaining value(s) must be equal to the known mean. O B. Of then values, can be freely selected because the remaining value(s) can be expressed in terms of the mean, median, and midrange of the assigned values. O C. Of then values, can be freely selected because the remaining value(s) can be expressed in terms of the assigned values and the known…

Given the mean and SD of the eight forms of employment in PEAR INC., calculate the z-scores for the individuals who took the exams in the different countries. ROUND Z-SCORES TO THREE DECIMAL PLACES; WRITE Z-SCORES WITH A SIGN (ex. -1.204 for negative z-score and +1.204 for positive) Description Quiz 11: Z-Scores   ROUND Z-SCORES TO THREE DECIMAL PLACES (to the nearest thousandth). EACH Z-SCORE SHOULD HAVE A + OR - SIGN IN FRONT TO INDICATE POSITIVE OR NEGATIVE VALUE. Use the data below: Eight forms of an employment exam (one in each country of expansion) are given by PEAR INC.  The overall (population) mean and standard deviations of these eight forms are found in the table below.

Q6. Select the best response. The sampling distribution of the mean will be approximately Normaleven when the population is not exactly Normal as long as the sample is: A. medium B. large C. small

A cup of coffee served at a restaurant's temperature.c. The number of no-shows for every 100 commercial airline reservations.d. The number of automobiles owned by a household chosen at random.e. The average amount spent on electricity by a randomly selected household ineach state during the month of July.

Using the data attached, compute x-bar: 1. Define the random variable x-bar in words 2. state the estimated distribution to use. Use both words and symbols.

The set of all possible values of a sample statistic is called a   A. simple random sample. B. point estimate. C. census. D. sampling distribution.

Toss five fair coins and let x equal the number of heads observed. a. Identify the sample points associated with this experiment, and assign a value of x to each sample point. Then list all the possible values of x. b. Calculate p(x) for the values x = 1 and x = 2. c. Construct a probability histogram for p(x). d. What is P(x = 1 or x = 4)?
