Here in this question we have a table for the result of survey regarding to the age group which are not a person has registered the physician.
00:12
So first of all we have to see the table.
00:15
So here is the table the visited physician yes or no and here is the age groups young old.
00:21
So those persons who have visited young ones are 35 and who are not rebuted are 1204.
00:32
Row total is 155 and similarly for old those who are visited are 42 and not visited 63 total are equal to 105 and here is the row and column total 260 so the first part of the question part a we need to find the marginal distribution marginal distribution so we will simply apply the distribution for each individual variable here.
01:05
So first the margin distribution, visit physician, visited, position will be as yes.
01:19
For those who have visited yes one, this will be as 42 added by 35, will be equal to 77 as it is given over here in the table.
01:35
And the no ones will be as 120 plus 63, which is.
01:40
183.
01:43
So now our value for the margin of distribution is the percentage in the percentage terms out of 216.
01:56
So here yes will you calculated as 77 divided by 260 which is equal to 0 .2961 and for known.
02:08
I have to divide 183 divided by 460 the total which is equal to to 0 .7038.
02:17
So here is the answer for the a part, the marginal distribution is 0 .296120 .0 .78.
02:31
So here we have our first solution of the given question...
