A researcher wants to study the academic performance of urban secondary schools in his county. He decides to measure each school's academic performance by collecting data on the percentage of students passing at least one Advanced Placement (AP) exam. The following table shows each school with the percentage of students passing at least one AP exam. No. School 1 Booker T.

How do I construct a frequency table with grouped data with the following problem? I would also like to know how the frequency scores are calculated from the interval data. Suppose we have collected weights from 100 male subjects as a part of a nutrition study. For our weight data, we have values ranging from a low of 121 pounds to a high of 263 pounds, giving the total span of 263-121=142. Determine reasonable class intervals for a frequency table.
5. The female students in an undergraduate engineering core course at UH self-reported their heights to the nearest inch. The data is as follows. 62 64 61 67 65 68 61 65 60 65 64 63 59 68 64 66 68 69 65 67 62 66 68 67 66 65 69 65 69 65 67 67 65 63 64 67 65 First construct the frequency distribution Table like Table 6-4 on Page 213 of textbook where you only need to specify the classes/bins, frequency info. Then using the table to create the histogram; here let the height of rectangle (for each bin) equal to the frequency instead of relative frequency in your histogram even though you can also set the height as the relative frequency. Hint: create the frequency distribution table by hand, but you can create the histogram in Excel and insert the result as a figure.
Table 3 shows the distribution for the number of medical leaves (in days) taken within a certain period by 65 employees of accompany. Number of medical leaves Number of employees (days) 1-3 4 4 -6 7-9 8 10 - 12 12 13 - 15 18 16 - 18 11 19 - 21 Table 3: The number of medical leaves (in days) (a) Draw a cummulative frequency curve to illustrate the data. (Note : Use graph sheet) (b) Using the ogive in question 4(a), estimate the median and third quartile value. (c) Calculate the mean, and standard deviation from the data given in Table 3.
Convinced about the importance of data processing through of statistics, Matheus, a production engineer, needs to do an analysis of the following data, which refers to daily production, in tons, from a company that operates in the processing industry of sugar cane. b) In addition to organizing the data in the frequency distribution, it is important to interpret the data. So Matheus performs the interpretation of the following data. - The interpretation of the absolute frequency of the third class. - The interpretation of the relative frequency of the second class. - The interpretation of the accumulated absolute frequency of the fourth class. What is the correct interpretation performed by Matheus for the previous questions?

The data to the right represent the top speed (in kilometers per hour) of all the players (except goaltenders) in a certain soccer league. Construct (a) a relative frequency distribution (b) a frequency histogram, and (c) a relative frequency histogram. What percentage of players had a top speed between 14 and 17.9 km/h? What percentage of players had a top speed less than 13.9 km/h? Speed (km/hr) Number of Players 10–13.9 4 14–17.9 8 18–21.9 18 22–25.9 76 26–29.9 268 30–33.9 177 (a) Construct a relative frequency distribution. Speed (km/hr) Relative Frequency 10–13.9 14–17.9 18–21.9 22–25.9 26-29.9 30–33.9 (Round to four decimal places as needed.)
