The following is the distribution of weights (in kg) of 50 persons: Marks:, 50-55, 55-60, 60-65, 65-70, 70-75, 75-80, 80-85, 85-90 No. of Person, 12, 8, 5, 4, 5, 7, 6, 3 Draw a histogram for the above data.

The daily wages of 30 workers (in Rs.) in a factory is given below. 40, 45, 35, 70, 60, 52, 49, 46, 65, 56, 60, 35, 45, 40, 50, 56, 57, 48, 55, 52, 50, 70, 75, 80, 50, 45, 52, 65, 72, 50. How many workers are earning less than Rs. 50 per day ?

Range of data: 20,40,30,60,80,100,10,70 is:

Range of data : 20,40,30,60,80,100,10,70 is

The following table gives the marks scored by 100 students in an entrance examination. Marks:, 0-10, 10-20, 20-30, 30-40, 40-50, 50-60, 60-70, 70-80 No. of Students (Frequency):, 4, 10, 16, 22, 20, 18, 8, 2

Consider the marks obtained (out of 100 marks) by 30 students of Class IX of a school: 10 20 36 92 95 40 50 56 60 70 92 88 80 70 72 70 36 40 36 40 92 40 50 50 56 60 70 60 60 88 Recall that the number of students who have obtained a certain number of marks is called the frequency of those marks. For instance, 4 students got 70 marks. So the frequency of 70 marks is 4. To make the data more easily understandable, tabulate the data.

Given the following frequency distribution with some missing frequencies class, 10-20,20-30,30-40,40-50,50-60,60-70,70-80 Frequency 180 , - , 34, 180 , 136 , - , 50 If the total frequency is 685 and median is 42.6 then the missing frequencies are
