 Hello and welcome to the session I am Deepika here. Let's discuss the question which says, A life insurance agent found the following data for distribution of ages of 100 policy holders. Calculate the median age. If policies are given only to persons 18 years onwards but less than 60 years. Now, if the age is below 20 years then the number of policy holders is true. Age is below 25 years then the number of policy holders is 6. And below 30 years it is 24. Below 35 it is 45. Below 40 it is 78. Below 45 it is 89. And below 50 it is 92. Below 55 it is 98. And below 60 it is 100. To know that the frequency of the formula median is equal to is the more limit of the median class, the number of observations, the frequency, the idea to solve the above question. For the solution question we have to calculate the median age. We need to find the class intervals and their corresponding frequencies. Distribution. If frequency distribution of less than time, here 20, 25, 30, 35, 40, 45, 50, 55, 60 minutes of the respective classes. Should be below 20, 22, 25, 25 to 30, 45, 45 to 50, 50 to 55 for the class interval. Below 20, 225, 235, 40, 40 to 45, 250, frequency of the years. Then the number of policy holders. The frequency of class interval below 20 is the holders. The number of policy holders in the group. So the frequency of the holders is 24, which is 21, which is 35, which is 33. And the frequency of the class is 9 minus 78, which is 11. And frequency of the class 45, 58 minus 92, the frequency of the class 55 to 60 is 100 minus 98, which is 224, 45, 70, 92, 100. Frequency distribution table with the given cumulative frequencies. The class whose cumulative frequency is greater than a frequency which is a low limit of the median class is 35. Now, cumulative frequency to frequency of this is equal to 45. The idea, the formula for these values in the formula median is equal to L plus N by 2 minus C F upon F into H. We get median is equal to 45 plus 25 upon 33 equal to 0.76 equal to 5.76. So, this is equal to 35.76. The other question is, median age is equal to 5.76 years. I hope the solution is good to you.
