Alright, so in the given question, we have to conduct a hypothesis test.
00:04
So our null hypothesis here is that population proportion is 0 .50.
00:09
And the sorry, this is 0 .55.
00:12
And the alternative is that the population proportion is different from 0 .55.
00:17
Right.
00:17
So this is a two tailed hypothesis test.
00:21
Now the size of the sample here is 1011.
00:24
And sample proportion is 0 .60.
00:27
Right.
00:27
So here, our test statistic value is computed by the formula that is sample proportion minus population proportion, divided by standard error.
00:39
So this is equal to 0 .60 minus 0 .55, divided by square root of 0 .55 into 1 minus 0 .55, divided by 1011.
00:52
So this is equal to 3 .20...
