If one of these 15,000 workers is selected at random, find the probability that this worker lost his or her job (a) because the company closed down or moved (b) due to insufficient work (c) because the position was abolished (d) Do these probabilities add to 1.0? If so, why? Problem 6 Two balanced dice are rolled. Of them, 7400 lost their jobs because their companies closed down or moved, 4600 lost their jobs due to insufficient work, and the remainder lost their jobs because their positions were abolished. Problem 5 In a large city, 15,000 workers lost their jobs last year. How many total outcomes are possible? Write these outcomes in a sample space. (Assume that there is no other outcome such as "no opinion" and "do not know.") Three persons are selected at random from this group and their opinions in favor or against raising such taxes are noted. What is the median of the exam scores To find the median, we need to identify the vertical line inside the box. Problem 4 In a group of people, some are in favor of a tax increase on rich people to reduce the federal deficit and others are against it. The following box plot shows the distribution of scores on a certain college exam. (d) None of the students suffers from math anxiety. (c) The first student does not suffer and the second suffers from math anxiety. (b) Exactly one student suffers from math anxiety. Indicate which are simple and which are compound events (a) Both students suffer from math anxiety. List all the outcomes included in each of the following events. (NE stand for north east, MW stand for mid-west, S stand for south, WE stand for west) Problem 3 Two students are randomly selected from a statistics class, and it is observed whether or not they suffer from math anxiety. Write two line to explain behavior of Box plot and Histogram. Also plot ordered stem-and-leaf, dotplot, Box-and-Whisker plot, Histogram using cut point approach(first class from 127 to less than 128). Problem 1 For given data for population, find Mean, Median, Mode, variance, standard deviation three quartiles Q 1 , Q 2 , Q 3 , Range, Max,Min,IQR,Outliers.
