A class teacher has the following attendance record of 40 students of a class of for the whole term . Find the mean number of days a student was present out of 56 days in the term . {:("Number of days","Number of students"),(35-38,1),(38-41,3),(41-44,4),(44-47,4),(47-50,7),(50-53,10),(53-56,11):}

Construct the frequency polygons of the following frequency distributions. Runs scored by students of a class in a cricket friendly match.

For a group of 100 students, the mean bar(x)_(1) and the standard deviation sigma_(1) of their marks were found to be 40 and 15 respectively. Later it was observed that the scores 40 and 50 were misread as 30 and 60 respectively. If the mean and the standard deviation with the corrected observations of the scores, are bar(x)_(2) and sigma_(2) respectively , then

Test scores out of 100 for a class of 19 students are as follows: 93, 84, 97, 98, 100, 78, 86, 100, 85, 92, 55, 91, 90, 75, 94, 93, 60, 81, 95 (a) Make a frequency table taking class interval as 91-100, 81-90, ... (b) Find the modal class (The "Modal class" is the class containing the greatest frequency). (c) find the interval that contains the median.
