In the given question, 60 adults with gum diseases were asked the number of times per week they used to flows before their diagnosis.
00:10
And the table is shown with incomplete results.
00:14
In part a, we need to fill the table.
00:18
Now, the table is given as flossing per week.
00:32
Frequency relative frequency and cumulative frequency frequency now closing per week 027 27 here it is 27 and in relative frequency 0 .4500 here also 0 .4 5000 this is 18.
01:30
And here we will calculate 18 over 60 which is equals to 0 .3000.
01:40
And here we will calculate 0 .45 plus 0 .30 which will be equals to 0 .75 which will be equals to 0 .75000.
02:00
Now this will calculate it will be 60 minus 27 plus 18 we will add all the frequencies on subject from 16.
02:13
Plus 18 plus 3 plus 1.
02:19
We will get 11.
02:21
And here in relative frequency 11 over 60.
02:26
We will divide frequency by 60.
02:29
Will give 0 .1833 and cumulative relative frequency will be 0 .75 this one plus this one 0 .183 this will give 0 .9333 now when it is 6 frequency is 3.
02:58
Relative frequency is 3...
