Okay, so from the given data, we can see that the sample size, so let's write down the given.
00:06
So the sample size equals, it's also known as n, is 36.
00:14
So, and the sample mean, so sample mean, which is also, part of you like that, is equal to 24 .7.
00:30
And the standard deviation, standard deviation, or that symbol is equal to two.
00:38
And then we also know that, whoops, i drew simple 1, is equal to 0 .05.
00:52
So now that we know this all the given.
00:54
So the claim is that the average age of lifeguards is greater than 24 years.
00:59
So therefore, how is equal to 24, and how is equal to 24, this corresponds to the right tail test.
01:14
So for this, it's going to equal 0 .05...
