14. Suppose the following data represent the number of persons unemployed for a given number of months in Killeen, Texas. The values in the first column show the number of months unemployed and the values in the second column show the corresponding number of unemployed persons. Months Unemployed Number Unemployed 1,029 1,686 3 2,269 4 2,675 3,487 4,652 4,145 3,587 9. 2,325 10 1,120 Let x be a random variable indicating the number of months a randomly selected per- son is unemployed. a. Use the data to develop an empirical discrete probability distribution for x. b. Show that your probability distribution satisfies the conditions for a valid discrete probability distribution. c. What is the probability that a person is unemployed for two months or less? Unem- ployed for more than two months? d. What is the probability that a person is unemployed for more than six months?

The following list gives the number of public libraries in each of 8 cities. 8, 8, 11, 7, 10, 7, 9, 9   Find the modes of this data set. If there is more than one mode, write them separated by commas. If there is no mode, click on "No mode."

(Please explain what I was doing wrong)

Set A: n = 5; x = 10Set B: n = 50; x = 10(a) Suppose the number 32 is included as an additional data value in Set A. Compute x  for the new data set.  To compute x for the new data set, add 32 to x of the original data set and divide by 6. (Round your answer to two decimal places.) b.) Suppose the number 32 is included as an additional data value in Set B. Compute x for the new data set. (Round your answer to two decimal places.)

6. A social worker looks at data in her state regarding the relationship between being in foster care and having a criminal record by the age of 25. "Aging out' refers to when a youth turns 18 years old and is expected to move out of foster care and start their lives on their own. Fictional data fro 1350 youths is shown below. Answer the following questions in the space below, labeling each response a, b, or c. What percentage of youths overall were adopted before aging out, and had a criminal record?                           What percentage of youths were in foster care until they were aged out?                           True or False: If foster care status and having a crime record were independent of each other, and 55% overall had no crime record, you would expect 55% of those who aged out in foster care to have no crime record.       No crime record Crime record Total Foster care until ‘aged out’ 445 450 895 Adopted before aging out 300 155…
