Complete Question
The histogram from this question is shown on the first uploaded image
Answer:
The first quartile is 
The median is 
The third quartile is
The mean is 
Step-by-step explanation:
From the question we are told that
The total number of girls is n = 74
Generally the median is mathematically represented as
![Median = \frac{\frac{n}{2} +[ \frac{n}{2} + 1] }{2}](https://tex.z-dn.net/?f=Median%20%20%3D%20%20%5Cfrac%7B%5Cfrac%7Bn%7D%7B2%7D%20%20%2B%5B%20%5Cfrac%7Bn%7D%7B2%7D%20%2B%201%5D%20%20%7D%7B2%7D)
So
![Median = \frac{\frac{74}{2} +[ \frac{74}{2} + 1] }{2}](https://tex.z-dn.net/?f=Median%20%20%3D%20%20%5Cfrac%7B%5Cfrac%7B74%7D%7B2%7D%20%20%2B%5B%20%5Cfrac%7B74%7D%7B2%7D%20%2B%201%5D%20%20%7D%7B2%7D)
=> 
=>
From the histogram
fall under 2 fruits per day
Generally the first quartile is mathematically represented as
![1st \ Q = \frac{\frac{n}{4} + [\frac{n}{4} + 1] }{2}](https://tex.z-dn.net/?f=1st%20%5C%20Q%20%3D%20%20%5Cfrac%7B%5Cfrac%7Bn%7D%7B4%7D%20%2B%20%5B%5Cfrac%7Bn%7D%7B4%7D%20%2B%201%5D%20%20%7D%7B2%7D)
=> ![1st \ Q = \frac{\frac{74}{4} + [\frac{74}{4} + 1] }{2}](https://tex.z-dn.net/?f=1st%20%5C%20Q%20%3D%20%20%5Cfrac%7B%5Cfrac%7B74%7D%7B4%7D%20%2B%20%5B%5Cfrac%7B74%7D%7B4%7D%20%2B%201%5D%20%20%7D%7B2%7D)
=> 
From the histogram
girl fall under 1 fruit per day
Generally the third quartile is mathematically represented as

=> 
=> 
From the histogram
fall under 4 fruits per day
Generally from the histogram table the frequency [number of subjects (girls) ] and the servings of fruit per day can be represented as
Total
x(servings per day ) 0 1 2 3 4 5 6 7 8
f (number of subjects ) 15 11 15 11 8 5 3 3 3 
xf 0 11 30 33 32 25 18 21 24 
Generally the mean is mathematically represented as
![\= x = \frac{1}{ \sum f} * [\sum xf]](https://tex.z-dn.net/?f=%5C%3D%20x%20%3D%20%5Cfrac%7B1%7D%7B%20%5Csum%20f%7D%20%20%2A%20%5B%5Csum%20xf%5D)
