Thank you We sneak And here's your shmoop du jour

00:06

brought to you by our favorite color electric line incidentally

00:11

our least favorite fruit Yeah electric line below is a

00:15

frequency distribution for favorite color among five year old girls

00:20

right here what's the relative frequency for the color purple

00:27

and hear the potential answers in a book partying and

00:32

allow surprising we really would have thought purple would have

00:35

gotten more love and who knew red was such a

00:38

hit it's like we don't know these little people at

00:40

all all right so the question wants to know what

00:43

the relative frequency is of the color purple and yet

00:46

not the book or the movie let's not make things

00:48

more complicated than they need to be Looking over our

00:51

answer choices we can roll option a into a ball

00:54

and toss it into the nearest trash can because relative

00:56

frequency is always a percentage and option c while tempting

01:01

since there's a five here in a five here is

01:03

not going to seduce us into making a poor decision

01:07

when they really make things that obvious we've seen with

01:09

these people are capable of and we're leaning toward no

01:12

to find relative frequency We always have to take the

01:15

number of a particular item and divided by the total

01:19

In this case we've got five five year old girls

01:22

who have a purple obsession and a total of forty

01:26

two girls So we divide that five by forty two

01:28

and five divided by forty two Well let's just get

01:31

our calculator friend's opinion here Uh yes eleven point nine

01:35

percent answer b We really want to meet the one

01:38

girl who chose other than not knowing is killing us

01:42

like it was it shark truce Tope eggplant yeah what 00:01:46.126 --> [endTime] a rebel
