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.ProbabilityProbabilityx4036.53329.528.5(Type integers or fractions.)b.

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.
