The daily wages of 80 workers in a project are given below.
Use a graph paper to draw an ogive for the above distribution. (Use a scale of 2 cm = Rs.
50 on x-axis and 2 cm = 10 workers on y-axis). Use your ogive to estimate:
1) the median wage of the workers
2) the lower quartile wage of workers
3) the numbers of workers who earn more than Rs. 625 daily
The marks obtained by 100 students in a Mathematics test are given below:
Draw an ogive for the given distribution on a graph sheet.
Use a scale of 2 cm = 10 units on both axes.
Use the ogive to estimate the:
2) Lower quartile.
3) A number of students who obtained more than 85% marks in the test.
4) A number of students who did not pass in the test if the pass percentage was 35.
The weight of 50 workers is given below:
|Weight in Kg||50-60||60-70||70-80||80-90||90-100||100-110||110-120|
|No. of Workers||4||7||11||14||6||5||3|
Draw an ogive of the given distribution using a graph sheet. Take 2 cm = 10 kg on one axis and 2 cm = 5 workers along the other axis. Use a graph to estimate the following:
1) The upper and lower quartiles.
2) If weighing 95 kg and above is considered overweight, find the number of workers who are overweight.
