An outlier is a datapoint outside of the first or third quartile +/- 1.5 the inter quartile range

25 33 39 40 41 41 45 46 48 49 51 52 67 73 79

46 is at the center-> median
everything left of it:
25 33 39 40 41 41 45
40 at center=Q1
right of Q2:
48 49 51 52 67 73 79
52 at center=Q3

IQR=Q3-Q1=52-40=12

Q1-1.5*IQR=40-1.5*12=40-18=22
Q3+1.5*IQR=52+1.5*12=52+18=60

so everything <22 or >60 are outliers

so 67,73 and 79 are outliers

Answer:

This is required solution

Step-by-step explanation:

Given that:

for male

joy = 28

happiness = 20

love = 40

anger = 18

a] we need to calculate the percentage of emotions for the male

using formula for percentage

$\percentage\ of\ emotions=\dfrac{emotion}{total\ emotions}\times100$

percentage of joy = $\dfrac{28}{106}\times100$

percentage of joy = 26.41

percentage of happiness = $\dfrac{20}{106}\times100$

percentage of happiness = 18.86

percentage of love = $\dfrac{40}{106}\times100$

percentage of love = 37.73

percentage of anger = $\dfrac{18}{106}\times100$

percentage of anger = 16.98

for female

joy = 61

happiness = 25

love = 80

anger = 60

we need to calculate the percentage of emotions for the female

using formula for percentage

$\percentage\ of\ emotions=\dfrac{emotion}{total\ emotions}\times100$

percentage of joy = $\dfrac{61}{226}\times100$

percentage of joy = 26.99

percentage of happiness = $\dfrac{25}{226}\times100$

percentage of happiness = 11.06

percentage of love = $\dfrac{80}{226}\times100$

percentage of love = 35.39

percentage of anger = $\dfrac{60}{226}\times100$

percentage of anger = 26.54

B] We need to draw a bar graph for male and female

using percentage of emotion of male and female

according to using percentage we draw a bar graph using data of part A.

Hence, this is required solution
