Hey there, welcome to numerate.
00:03
We're given the ages and years and the relative frequency, or the respective frequencies here, with a total of 65 attendees.
00:15
So this blank over here was given empty.
00:19
So how i calculated, this was basically taken the 65 or total and minus it from the rest.
00:27
12 plus 15 plus 32 and i use this equation over here and what i got is 6 equals 6 right so with that now um we've actually find a median so median age and years so median equals basically the middle value right so let's just eyeball it over here so if we have 32 and we add up d three on top so i'm saying if we add up these three over here what will we get okay let's see what we get so we're gonna add those so we have 12 plus 15 plus six so that will equals 17 plus 6 is 23 so it'll be 23 and you can see this will be 32 right from 30 1 to 40 would 32 so it will be in this area right here 31 to 40.
01:52
Okay, so this is a possible age.
01:55
And what we've given here is four values, four choices, 1928, 32, 32, 38.
02:03
So 38 is really high in that value.
02:07
So it's either just 32 and 38, right? but if you look over here, so what we have is either 32 or 38.
02:21
Because we're looking at the interval from 31 to 40 with the highest frequency, right? and so 23 is pretty close, right? so let's see over here.
02:36
So find a median.
02:38
So let's add a 65 divided by 2 to find a median.
02:43
And that will just basically be, should be 32 .5.
02:52
So therefore, since this is 23 and very close to 30.
02:56
2 .5.
03:00
Let me see here.
03:04
Let me see and 23.
03:14
Okay.
03:15
So i'm miscalculated here...
