For this question, we are told that a test statistic of z equals 0 .85 is obtained when testing the claim that the population proportion is greater than 0 .2.
00:14
Now we are first asked to identify the hypothesis test as being 2 -tailed, left -tailed, or right -tailed.
00:23
To do this, we look at the claim.
00:25
The proportion is greater than 0 .2.
00:27
So that is the alternative hypothesis.
00:37
The null hypothesis would be that the proportion is either equal to 0 .2 or no greater than 0 .2.
00:48
So either this, no greater than or equal to.
00:54
And to determine if the test is left -tailed, right -tailed, or two -tailed, we look at the alternative hypothesis.
01:01
Here we can see that it's a greater -than -hypothesis.
01:04
This means that the test is right -tailed.
01:14
So this is a right -tailed test.

And the second part is defined the p -value...
