(a) Draw a relative frequency histogram with lower class limit of the first class equal to 0 and class width 20.

4). Using the data in the question #2, construct a histogram and then construct a frequency polygon.

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.

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,
