Hello, let's have a look on the question.
00:03
So here, the sample size is given to us, n is equal to 800, and p -caf, the sample proportion is equal to 0 .30.
00:13
Now, the claim is that 28 % of adult in a certain country would travel into space on a commercial flight if they could afford it.
00:21
So the null and alternating hypothesis, that is h -0, p is equal to 0 .28, and h of a, that is, p is not equal to 0 .28.
00:34
Now, alpha is given to us 0 .10.
00:38
Now, we need to first find out the test statistics.
00:44
So for test statistics, we will be using the formula, that is, z is equal to p -cap minus p divided by under root of p into, or p multiplied by 1 minus p upon n...
