Answer 1

A stem leaf plot is kinda like a frequency table and a histogram, let's start with that.

We'll group the data by tens, by leading digit, shown in bold.  For each day we write the ones digit after the leading digit.

5 613

6 3

7 42742685

8 66814957

9 4021

Now we just count of the days for the frequency table,

range  count

50-59 3

60-69 1

70-79 8

80-89 8

90-99 4

Now we have to make a histogram; the stem leaf table pretty much is one; let's replace the data by *

50-59 ***

60-69 *

70-79 ********

80-89 ********

90-99 ****
