Bonus #1 (descriptive statistics) A test has been applied to the employees of a Pharmaceutical Company, obtaining the following table: [38, 44) V [44, 50) CO [50, 56) 15 [56, 62) 25 [62, 68) 18 [68, 74) 9 [74, 80) 6 Draw the histogram 1. The following graph shows the grades of a group of 38 students. W. 5% 7 A. 13% F. 8% B. 16% D, 32% C. 26% Calculate a. Number of students getting A b. How many students get C or better? c. How many students dropped out? d. How many students did not pass the class (earned For W)? 2. The weight in pounds of 10 Chopa fish in the Cidra reservoir is: 2, 4, 3, 6, 7, 2, 3, 2, 4, 5, Determine: a. Mode b. Average c. Median d. Range e. standard deviation, f. Variation coefficient3. We have the following set of 26 data: 10, 13, 4, 7, 8, 11, 10, 16, 18, 12, 3, 6, 9, 9, 4, 13, 20, 7, 5, 10, 17, 10, 16, 14, 8, 18. Obtain the 3 quartiles. 4. The histogram of the distribution corresponding to the weight of 100 high school students is as follows: 40- 42 27 20 - 18 8 0 5 60 63 66 69 72 75 a. Construct the table of the distribution of grouped data b. Find the mean and standard deviation. C. From what values are the 25% of the heaviest students? 5. If the mean of 3, 8, 9, 10, x is 7, calculate the value of x 6. A sample of ages is taken from 40 children who reside in the Estancias Monte rio neighborhood in Caguas. 5, 10, 12, 8, 12, 11, 2, 7, 8, 3, 9, 10, 8, 14, 10, 4, 9, 10, 1, 5, 12, 5,10, 12, 14, 13, 9, 5, 4, 3, 2, 12, 14, 15, 10, 9, 8, 7, 12, 14 a. Build a table of interval grouped data b. With the information in the table, construct the arithmetic mean, and the standard deviation. c. Draw the histogram
