The table shows the scores on a Chem 103 test consisting of 10 questions worth 10 points each. Supposethat the grading scale for the test is A: 80-100; B: 70-79; C: 60-69; D: 50-59; and F: 0-49. Complete parts (a)and (b).Chem 103 ScoresStudent # TestScoreStudent #1 90 13 102 90 14 03 70 15 704 60 16 405 60 17 506 80 18 707 80 19 708 60 20 909 80 21 8010 100 22 7011 90 23 9012 90 24 80TestScorea. Make a frequency table for the distribution of the testgrades by completing the table below.GradeA: 80-100B: 70-79C: 60-69D: 50-59E: 0-49Frequencyb. Make a bar graph showing the distribution of the testgrades. Choose the correct graph below.A. B.C. D.

3. Use the data in the grade-distribution table below to construct a pie chart showing the distribution of gradetypes in a class.Grade A B C D FChoose the correct pie chart.Frequency 3 7 11 2 14. The bar graph describes the scores of a group of students on a 10-point math quiz. Complete parts (a)through (c) to the right.a. How many students took the math quiz?b. What percentage of the students scored 2 points?c. If a grade of 6 or more was needed to pass the quiz, what percentage of thestudents passed?5. Use the pie chart to complete parts (a) through (c).a. Is cause of death a quantitative or qualitative variable?b. Based on the data provided in the pie chart, estimate thenumber of 18- to 22-year-olds who died in the populationstudied due to an accident. (Round to the nearest wholenumber)c. Estimate the size of the central angle of the slicerepresenting the category “Other”. (Round to the nearest degree)6. The pie chart represents the breakdown of the $2.9 trillion federal budget of a country’s last fiscal year.Note: $1 trillion = $1,000 billion. Use the pie chart tocomplete parts (a) and (b).a. Estimate how much money the federal government spenton last year’s defense. (Round to the nearest billion)b. Calculate the size of the central angle for each slice of thepie chart.
