Hello everyone, let's solve the given question.
00:02
So, as according to the question we have given n1 is equals to 484, n2 is equals to 709, x1 is equals to 80, x2 is equals to 100.
00:17
Then p1 cap is equals to x1 divided n1.
00:21
Then we get it equals to 0 .1653.
00:26
P2 cap is equals to x2 divided n2 is equals to 0 .1410.
00:33
Now alpha is equals to 0 .05.
00:37
H0 is p1 is equals to p2.
00:41
Ha is that the p1 is not equals to p2.
00:46
So, now as to be moving further according to the part a of the question test statistic z is equals to p1 cap minus p2 cap divided by under root p bar multiply 1 minus p bar multiply 1 divided n1 plus 1 divided n2.
01:11
So, now as to be moving further the p bar is equals to x1 plus x2 divided n1 plus n2...
