The temperatures for 6 days are as follows; 61, 71, 79, 62, 60, 93. Calculate the average temperature: round to 1 decimal place In the box-and-whisker plot below, what is the 2nd quartile? + 5 10 15 20 25 30 35 40 45 50 The box-and-whisker plot below represents students' scores on a recent English test. 60 70 80 90 100 Student Scores What is the value of the upper quartile? What is the IQR of the data represented in the box-and- whisker plot shown below? Q3-Q1 0 25 25 50 75 100 Find the Sample Variance if SS = 255 and the sample size = 8. Write your answer to 2 decimal places. Answer formula X n-1 Question 6 10 Points Find the Sample Standard Deviation if SS = 853 and the sample size = 10. Steps: 1] Find the Sample Variance - 55 SS N-1 2] Use the Sample Variance to find the STANDARD DEVIATION Write your answer to 2 decimal places Add your answer Question 7 10 Points Dr. Mendoza developed a test to measure boredom tolerance. He administered it to a group of 20,000 adults between the ages of 25 and 35. The possible scores were 0, 1, 2, 3, 4, 5, and 6, with 6 indicating the highest tolerance for boredom. The test results for this group are shown in Table below: Score 0 1 2345 6 Number of Subjects Probability P(x) 1400 0.07 2600 0.13 3600 0.18 6000 0.30 4400 0.22 1600 0.08 400 0.02 () = Boredom Tolerance Test Scores for 20,000 Subjects What is the sum of the Random Variable? Question 9 10 Points The Topnotch Clothing Company needs to hire TWO Persons with a score on the boredom tolerance test of 2 or 4 to work in the Sales Department. Using Dr. Mendoza's test to measure boredom tolerance, what is the probability of hiring TWO Persons from the group tested with a boredom tolerance test of 2 AND 4?

Market research predicts that if the airline serves New Orleans, there is a 42% probability of making a $700,000 profit. The up-front cost to maintian flights on the routh is $321,000. Should the airline proceed with plans for adding the route? Determine the Gain or Loss.
