3. Construct a frequency distribution of ages of 52 patients with positive covid 19 at hospital X from the given data. Using a class interval and include also the less than and greater than cumulative frequencies, and the class marks of every class interval. Also prepare a frequency polygon of the frequency distribution. 80 65 67 62 56 35 37 67 27 42 58 38 42 45 70 80 56 34 48 23 49 45 23 22 45 26 28 25 58 74 51 60 42 58 63 69 38 52 26 54 75 55 41 54 35 47 20 36 22 41 45 36

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.

One of the primary goals of constructing a frequency distribution for quantitative data is to summarize the data O by showing frequency of values that lie within a class or bin. O so that there are always 7 classes or bins of data. O ensuring that the classes or bins are always of different widths. O in a manner so that each class or bin has the same number of data points.
