00:01 So from the given table, the answer to the first part, that is mean, will be equal to summation of f of x minus divided by the summation of f.
00:11 So this is divided by the summation of f.
00:15 So we are having the value of summation of f from the table we have calculated that is 9 to 96 and the value of summation of f will be 298.
00:24 So plugging in this value in the formula of mean, so mean will be equals to 9 to 9 to 9 .99.
00:30 96 divided by the 298, that will be equals to 31 .194.
00:36 The answer to the second part is we have to find out the value of median and the value of median will be equals to l plus n of 1 minus c of f divided by the f, which is multiplied by the c.
00:51 So we are having the value of n1 that will be equal to summation of f divided by the 2, that will be equals to 298 divided by 2, which will be equals to 1 .4...
