shows a frequency distribution of the weekly wages of 65 employees at the P&R Company. Table1 Wages Number of employees 250.00 - 259.99 8 260.00 - 269.99 10 270.00 - 279.99 16 280.00 - 289.99 14 290.00 - 299.99 10 300.00 - 309.99 5 310.00 - 319.99 2 Total 65 With reference to this table, determine: The lower limit of the sixth class. The upper limit of the fourth class. The class mark (or class midpoint) of the third class. The class boundaries of the fifth class. The size of the fifth-class interval. The frequency of the third class. The relative frequency of the third class. The class interval having the largest frequency. This is sometimes called the modal class interval; its frequency is then called the modal class frequency. The percentage employees earning less than $280.00 per week. The percentage employees earning less than $300.00 per week but at least $260.00 per…
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.
The owner of an automobile repair shop studied the waiting times for customers who arrive at the shop for an oil change. The following data with waiting times in minutes were collected over a one-month period. 3 4 10 214 5 3 2310 11 9 166 14 6 92 22 16 7(a) Develop a frequency distribution using classes of 0-4, 5-9, 10-14, 15-19, and 20-24.Class Frequency 0-4 5-9 10-14 15-19 20-24 Total (b) Develop a relative frequency distribution using the classes in part (a). If required, round your answers to two decimal places. Class Relative Frequency 0-4 5-9 10-14 15-19 20-24 Total (c) Develop a cumulative frequency distribution using the classes in part (a).

Average monthly wages (per employee) in 4 sectors of an economy are as follows: industry: 2000 dinars, building: 2200 dinars, agriculture: 1500 dinars, services: 1800 dinars. Number of people employed in the four sectors are 5 million, 2 million, 6 million, and 2 million, respectively. Using the concept of harmonic mean compute the average monthly wages in the economy under consideration.
