In this question we are given that the value of x is 50 and here the sample size is equal to 190.
00:12
P is equal to proportion is 20%, which is equal to 2500 as 0 .20.
00:25
So 1 minus p the probability for q will be 1 minus 0 .20 which is equal to 0 .80 which is equal to 0 .80.
00:34
0.
00:36
So now let's solve our first part of the question.
00:38
Here we will set our hypothesis first.
00:42
So hypothesis for this question are our null hypothesis, ho, is to peel less than or equal to 0 .20.
00:56
And our alternative hypothesis here, so p is greater than 0 .20.
01:02
And here we need to check for the right tamed test for the given hypothesis.
01:15
And after that, we will find our party solution for this same question.
01:21
Here you will find i will refer n into p which will be value of n is 190 and value for p is 0 .20.
01:35
So we have to multiply these two values which are equal to 38.
01:41
And on the next step we will find n include 1 minus p...
