The frequency distribution of the marks obtained by 76 students in a math. Find the average of marks obtained . {:("Numbers obtained",1-10,11-20,21-30,31-40,41-50,"Total"),("Frequncies",4,14,32,18,8,76):}

Draw a histogram for the following {:("Class interval ", 11-20,21-30,31-40,41-50,51-60),(" Frequency "," "5, " "8, " "13 , " "10, " "6):}

Caculate median of the following distribution of data : {:("Class Interval",1-10,11-20,21-30,31-40,41-50),("Frequency"," "4," "12," "20," "9," "5):}

The median class in the following frequency distribution is {:("Class interval :",0-10,10-20,20-30,30-40,40-50),("Frequency :",12,13,25,20,10):}

The median class in the following frequency distribution is {:("Class interval :",0-10,10-20,20-30,30-40,40-50),("Frequency :",12,13,25,20,10):}

For the following frequency distribution draw a cumulative frequency curve of "'more than type'" and hence obtain the median value [["Class",0-10,10-20,20-30,30-40,40-50,50-60,60-70],["Frequency",5,15,20,23,17,11,9]]

Draw a histogram of the following data: Class interval: 10-15, 15-20, 20-25, 25-30, 30-35, 35-40, Frequency: 30, 98, 80, 58, 29, 50,

Estimate the mode of the following data from the histogram. {:("Class Interval",0-10,10-20,20-30,30-40,40-50,50-60,60-70,70-80),("Frequency",8,10,15,16,20,13,14,12):}

Find the mean for the following data : {:("C.I",0-10,10-20,20-30,30-40,40-50,),("f"," 3"," 5"," 3"," 9"," 5",):}

Draw a frequency curve for the data given below: {:("Class Interval",0-10,10-20,20-30,30-40,40-50,50-60,60-70),("Frequency",3,2,4,6,9,7,10):}
