Question

1. Collect the height (in cm) and weight (in kg) of 4 – 5 members of your family.
2. Prepare bar graph for the above collected data (i.e. height and weight).
3. Calculate BMI (body mass index) for each member.
4. Calculate average height for the collected data.
5. Calculate average weight for the collected data.

Answer 1

Step-by-step explanation:

This is your project work so try to do it by yourself but I am giving you one example :-

Number of

Q1)

family :- 5

height (in cm )

5cm

10cm

15cm

20cm

25cm

weight (in kg)

5kg

10kg

15kg

20kg

25kg

Q2) you have to done it by urself

Q3) BMI = KG/m^2

for 1st person

h = 5cm w = 5kg

h = 5/100

h = 0.05m

BMI = 5/(0.05)^2

= 5/0.0025

= 2000/1000

= 2kg/m^2

Q4) average height = sum of height of the total people/number of total people

= 5+10+15+20+25/5

= 75/5

= 15

Q5) average weight = sum of weight of the total number of people/ number of total people

= 5+10+15+20+25/5

= 75/5

= 15
