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.
Resting Pulse: earlier this semester we determined our resting pulse. Seventy-nine individuals participated in this data collection. The mean heart rate for all individuals was 65.34 beats per minute. A random sample of 30 heart rates having a mean of 64.97 beats per minute is presented here. Build a frequency table of these data containing six (6) classes with the lower llimit of the second class at 54 beats per minute. Build a chart appropriate for the presentation of these data. Data: 49, 51, 53, 56, 57, 58, 60 , 60, 62, 62, 62, 64, 64 65, 65 , 65, 67, 68, 68, 68, 69, 70 , 70, 72, 72, 72, 72, 75, 75 , 78,
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?

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.
